2011-10-31fs: add module.h to files that were implicitly using itPaul Gortmaker9-0/+9
Some files were using the complete module.h infrastructure without actually including the header at all. Fix them up in advance so once the implicit presence is removed, we won't get failures like this: CC [M] fs/nfsd/nfssvc.o fs/nfsd/nfssvc.c: In function 'nfsd_create_serv': fs/nfsd/nfssvc.c:335: error: 'THIS_MODULE' undeclared (first use in this function) fs/nfsd/nfssvc.c:335: error: (Each undeclared identifier is reported only once fs/nfsd/nfssvc.c:335: error: for each function it appears in.) fs/nfsd/nfssvc.c: In function 'nfsd': fs/nfsd/nfssvc.c:555: error: implicit declaration of function 'module_put_and_exit' make[3]: *** [fs/nfsd/nfssvc.o] Error 1 Signed-off-by: Paul Gortmaker <paul.gortmaker@windriver.com>
2011-10-31fs: add export.h to files using EXPORT_SYMBOL/THIS_MODULE macrosPaul Gortmaker11-0/+11
These files were getting <linux/module.h> via an implicit include path, but we want to crush those out of existence since they cost time during compiles of processing thousands of lines of headers for no reason. Give them the lightweight header that just contains the EXPORT_SYMBOL infrastructure. Signed-off-by: Paul Gortmaker <paul.gortmaker@windriver.com>

2011-10-28leases: fix write-open/read-lease raceJ. Bruce Fields2-4/+5
In setlease, we use i_writecount to decide whether we can give out a read lease. In open, we break leases before incrementing i_writecount. There is therefore a window between the break lease and the i_writecount increment when setlease could add a new read lease. This would leave us with a simultaneous write open and read lease, which shouldn't happen. Signed-off-by: J. Bruce Fields <bfields@redhat.com> Signed-off-by: Christoph Hellwig <hch@lst.de>

2011-10-28vfs: do (nearly) lockless generic_file_llseekAndi Kleen5-50/+48
The i_mutex lock use of generic _file_llseek hurts. Independent processes accessing the same file synchronize over a single lock, even though they have no need for synchronization at all. Under high utilization this can cause llseek to scale very poorly on larger systems. This patch does some rethinking of the llseek locking model: First the 64bit f_pos is not necessarily atomic without locks on 32bit systems. This can already cause races with read() today. This was discussed on linux-kernel in the past and deemed acceptable. The patch does not change that. Let's look at the different seek variants: SEEK_SET: Doesn't really need any locking. If there's a race one writer wins, the other loses. For 32bit the non atomic update races against read() stay the same. Without a lock they can also happen against write() now. The read() race was deemed acceptable in past discussions, and I think if it's ok for read it's ok for write too. => Don't need a lock. SEEK_END: This behaves like SEEK_SET plus it reads the maximum size too. Reading the maximum size would have the 32bit atomic problem. But luckily we already have a way to read the maximum size without locking (i_size_read), so we can just use that instead. Without i_mutex there is no synchronization with write() anymore, however since the write() update is atomic on 64bit it just behaves like another racy SEEK_SET. On non atomic 32bit it's the same as SEEK_SET. => Don't need a lock, but need to use i_size_read() SEEK_CUR: This has a read-modify-write race window on the same file. One could argue that any application doing unsynchronized seeks on the same file is already broken. But for the sake of not adding a regression here I'm using the file->f_lock to synchronize this. Using this lock is much better than the inode mutex because it doesn't synchronize between processes. => So still need a lock, but can use a f_lock. This patch implements this new scheme in generic_file_llseek. I dropped generic_file_llseek_unlocked and changed all callers.

2011-10-28direct-io: inline the complete submission pathAndi Kleen1-15/+21
Add inlines to all the submission path functions. While this increases code size it also gives gcc a lot of optimization opportunities in this critical hotpath. In particular -- together with some other changes -- this allows gcc to get rid of the unnecessary clearing of sdio at the beginning and optimize the messy parameter passing. Any non inlining of a function which takes a sdio parameter would break this optimization because they cannot be done if the address of a structure is taken. Note that benefits are only seen with CONFIG_OPTIMIZE_INLINING and CONFIG_CC_OPTIMIZE_FOR_SIZE both set to off. This gives about 2.2% improvement on a large database benchmark with a high IOPS rate.

2011-10-28direct-io: separate map_bh from dioAndi Kleen1-29/+37
Only a single b_private field in the map_bh buffer head is needed after the submission path. Move map_bh separately to avoid storing this information in the long term slab. This avoids the weird 104 byte hole in struct dio_submit which also needed to be memseted early. Signed-off-by: Andi Kleen <ak@linux.intel.com> Signed-off-by: Christoph Hellwig <hch@lst.de>
2011-10-28direct-io: use a slab cache for struct dioAndi Kleen1-5/+14

2011-10-28direct-io: separate fields only used in the submission path from struct dioAndi Kleen1-188/+201
This large, but largely mechanic, patch moves all fields in struct dio that are only used in the submission path into a separate on stack data structure. This has the advantage that the memory is very likely cache hot, which is not guaranteed for memory fresh out of kmalloc. This also gives gcc more optimization potential because it can easier determine that there are no external aliases for these variables. The sdio initialization is a initialization now instead of memset. This allows gcc to break sdio into individual fields and optimize away unnecessary zeroing (after all the functions are inlined) Signed-off-by: Andi Kleen <ak@linux.intel.com> Acked-by: Jeff Moyer <jmoyer@redhat.com> Signed-off-by: Christoph Hellwig <hch@lst.de>

2011-10-28compat: sync compat_stats with statfs.Eric W. Biederman1-5/+2
This was found by inspection while tracking a similar bug in compat_statfs64, that has been fixed in mainline since decemeber. - This fixes a bug where not all of the f_spare fields were cleared on mips and s390. - Add the f_flags field to struct compat_statfs - Copy f_flags to userspace in case someone cares. - Use __clear_user to copy the f_spare field to userspace to ensure that all of the elements of f_spare are cleared. On some architectures f_spare is has 5 ints and on some architectures f_spare only has 4 ints. Which makes the previous technique of clearing each int individually broken. I don't expect anyone actually uses the old statfs system call anymore but if they do let them benefit from having the compat and the native version working the same. Signed-off-by: Eric W.

2011-10-25sysfs: Remove support for tagged directories with untagged members (again)Eric W. Biederman1-4/+4
In commit 8a9ea3237e7e ("Merge git://.../davem/net-next") where my sysfs changes from the net tree merged with the sysfs rbtree changes from Mickulas Patocka the conflict resolution failed to preserve the simplified property that was the point of my changes. That is sysfs_find_dirent can now say something is a match if and only s_name and s_ns match what we are looking for, and sysfs_readdir can simply return all of the directory entries where s_ns matches the directory that we should be returning. Now that we are back to exact matches we can tweak sysfs_find_dirent and the name rb_tree to order sysfs_dirents by s_ns s_name and remove the second loop in sysfs_find_dirent. However that change seems a bit much for a conflict resolution so it can come later. Signed-off-by: Eric W.

Remove it from the new location instead. - fs/sysfs/dir.c: Fairly nasty conflicts with the sysfs rb-tree usage, conflicting with Eric Biederman's changes for tagged directories.

2011-10-24ore: Enable RAID5 mountsBoaz Harrosh1-3/+11
Now that we support raid5 Enable it at mount. Raid6 will come next raid4 is not demanded for so it will probably not be enabled. (Until some one wants it) NOTE: That mkfs.exofs had support for raid5/6 since long time ago. (Making an empty raidX FS is just as easy as raid0 ;-} ) Signed-off-by: Boaz Harrosh <bharrosh@panasas.com>
