2012-07-22hfsplus: get rid of write_superArtem Bityutskiy1-3/+3
This patch makes hfsplus stop using the VFS '->write_super()' method along with the 's_dirt' superblock flag, because they are on their way out. The whole "superblock write-out" VFS infrastructure is served by the 'sync_supers()' kernel thread, which wakes up every 5 (by default) seconds and writes out all dirty superblocks using the '->write_super()' call-back. But the problem with this thread is that it wastes power by waking up the system every 5 seconds, even if there are no diry superblocks, or there are no client file-systems which would need this (e.g., btrfs does not use '->write_super()'). So we want to kill it completely and thus, we need to make file-systems to stop using the '->write_super()' VFS service, and then remove it together with the kernel thread. Tested using fsstress from the LTP project. Signed-off-by: Artem Bityutskiy <artem.bityutskiy@linux.intel.com> Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>

Just the flags; only NFS cares even about that, but there are legitimate uses for such argument. And getting rid of that completely would require splitting ->lookup() into a couple of methods (at least), so let's leave that alone for now... Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>

2011-07-20fs: push i_mutex and filemap_write_and_wait down into ->fsync() handlersJosef Bacik1-1/+9
Btrfs needs to be able to control how filemap_write_and_wait_range() is called in fsync to make it less of a painful operation, so push down taking i_mutex and the calling of filemap_write_and_wait() down into the ->fsync() handlers. Some file systems can drop taking the i_mutex altogether it seems, like ext3 and ocfs2. For correctness sake I just pushed everything down in all cases to make sure that we keep the current behavior the same for everybody, and then each individual fs maintainer can make up their mind about what to do from there.

2011-07-20fs: simplify the blockdev_direct_IO prototypeChristoph Hellwig1-2/+2
Simple filesystems always pass inode->i_sb_bdev as the block device argument, and never need a end_io handler. Let's simply things for them and for my grepping activity by dropping these arguments. The only thing not falling into that scheme is ext4, which passes and end_io handler without needing special flags (yet), but given how messy the direct I/O code there is use of __blockdev_direct_IO in one instead of two out of three cases isn't going to make a large difference anyway.

2010-11-23hfsplus: flush disk caches in sync and fsyncChristoph Hellwig1-0/+4
Flush the disk cache in fsync and sync to make sure data actually is on disk on completion of these system calls. There is a nobarrier mount option to disable this behaviour. It's slightly misnamed now that barrier actually are gone, but it matches the name used by all major filesystems. Signed-off-by: Christoph Hellwig <hch@tuxera.com>
2010-11-23hfsplus: optimize fsyncChristoph Hellwig1-8/+19
Avoid doing unessecary work in fsync. Do nothing unless the inode was marked dirty, and only write the various metadata inodes out if they contain any dirty state from this inode. This is archived by adding three new dirty bits to the hfsplus-specific inode which are set in the correct places. Signed-off-by: Christoph Hellwig <hch@tuxera.com>
2010-11-23hfsplus: split up inode flagsChristoph Hellwig1-3/+6

2010-11-23hfsplus: write up fsync for directoriesChristoph Hellwig1-1/+1

2010-11-23hfsplus: simplify fsyncChristoph Hellwig1-21/+20
Remove lots of code we don't need from fsync, we just need to call ->write_inode on the inode if it's dirty, for which sync_inode_metadata is a lot more efficient than write_inode_now, and we need to write out the various metadata inodes, which we now do explicitly instead of by calling ->sync_fs.

2010-10-14hfsplus: create correct initial catalog entries for device filesChristoph Hellwig1-25/+2
Make sure the initial insertation of the catalog entry already contains the device number by calling init_special_inode early and setting writing out the dev field of the on-disk permission structure. The latter is facilitated by sharing the almost identical hfsplus_set_perms helpers between initial catalog entry creating and ->write_inode. Unless we crashed just after mknod this bug was harmless as the inode is marked dirty at the end of hfsplus_mknod, and hfsplus_write_inode will update the catalog entry to contain the correct value.

2010-10-14hfsplus: remove superflous rootflags field in hfsplus_inode_infoChristoph Hellwig1-1/+0
The rootflags field in hfsplus_inode_info only caches the immutable and append-only flags in the VFS inode, so we can easily get rid of it. Signed-off-by: Christoph Hellwig <hch@tuxera.com>
2010-10-14hfsplus: fix link corruptionChristoph Hellwig1-6/+8
HFS implements hardlink by using indirect catalog entries that refer to a hidden directly. The link target is cached in the dev field in the HFS+ specific inode, which is also used for the device number for device files, and inside for passing the nlink value of the indirect node from hfsplus_cat_write_inode to a helper function. Now if we happen to write out the indirect node while hfsplus_link is creating the catalog entry we'll get a link pointing to the linkid of the current nlink value. This can easily be reproduced by a large enough loop of local git-clone operations. Stop abusing the dev field in the HFS+ inode for short term storage by refactoring the way the permission structure in the catalog entry is set up, and rename the dev field to linkid to avoid any confusion. While we're at it also prevent creating hard links to special files, as the HFS+ dev and linkid share the same space in the on-disk structure. Signed-off-by: Christoph Hellwig <hch@tuxera.com>
2010-10-01hfsplus: remove the rsrc_inodes listChristoph Hellwig1-1/+9

HFSPLUS_I doesn't return a pointer to the hfsplus-specific inode information like all other FOO_I macros, but dereference the pointer in a way that made it look like a direct struct derefence. This only works as long as the HFSPLUS_I macro is used directly and prevents us from keepig a local hfsplus_inode_info pointer.

2010-08-09remove inode_setattrChristoph Hellwig1-1/+11
Replace inode_setattr with opencoded variants of it in all callers. This moves the remaining call to vmtruncate into the filesystem methods where it can be replaced with the proper truncate sequence. In a few cases it was obvious that we would never end up calling vmtruncate so it was left out in the opencoded variant: spufs: explicitly checks for ATTR_SIZE earlier btrfs,hugetlbfs,logfs,dlmfs: explicitly clears ATTR_SIZE earlier ufs: contains an opencoded simple_seattr + truncate that sets the filesize just above In addition to that ncpfs called inode_setattr with handcrafted iattrs, which allowed to trim down the opencoded variant.

2008-10-23[PATCH] move executable checking into ->permission()Miklos Szeredi1-13/+0
For execute permission on a regular files we need to check if file has any execute bits at all, regardless of capabilites. This check is normally performed by generic_permission() but was also added to the case when the filesystem defines its own ->permission() method. In the latter case the filesystem should be responsible for performing this check. Move the check from inode_permission() inside filesystems which are not calling generic_permission(). Create a helper function execute_ok() that returns true if the inode is a directory or if any execute bits are present in i_mode. Also fix up the following code: - coda control file is never executable - sysctl files are never executable - hfs_permission seems broken on MAY_EXEC, remove - hfsplus_permission is eqivalent to generic_permission(), remove Signed-off-by: Miklos Szeredi <mszeredi@suse.cz>

2007-05-21Detach sched.h from mm.hAlexey Dobriyan1-0/+1
First thing mm.h does is including sched.h solely for can_do_mlock() inline function which has "current" dereference inside. By dealing with can_do_mlock() mm.h can be detached from sched.h which is good. See below, why. This patch a) removes unconditional inclusion of sched.h from mm.h b) makes can_do_mlock() normal function in mm/mlock.c c) exports can_do_mlock() to not break compilation d) adds sched.h inclusions back to files that were getting it indirectly. e) adds less bloated headers to some files (asm/signal.h, jiffies.h) that were getting them indirectly Net result is: a) mm.h users would get less code to open, read, preprocess, parse, ... if they don't need sched.h b) sched.h stops being dependency for significant number of files: on x86_64 allmodconfig touching sched.h results in recompile of 4083 files, after patch it's only 3744 (-8.3%).

This allows us to cleanup all variants of generic_file_* routines.
