2009-04-09module: try_then_request_module must waitHerbert Xu1-1/+1
Since the whole point of try_then_request_module is to retry the operation after a module has been loaded, we must wait for the module to fully load. Otherwise all sort of things start breaking, e.g., you won't be able to read your encrypted disks on the first attempt.

2009-04-09sched: do not count frozen tasks toward loadNathan Lynch1-1/+2
Freezing tasks via the cgroup freezer causes the load average to climb because the freezer's current implementation puts frozen tasks in uninterruptible sleep (D state). Some applications which perform job-scheduling functions consult the load average when making decisions. If a cgroup is frozen, the load average does not provide a useful measure of the system's utilization to such applications. This is especially inconvenient if the job scheduler employs the cgroup freezer as a mechanism for preempting low priority jobs. Contrast this with using SIGSTOP for the same purpose: the stopped tasks do not count toward system load. Change task_contributes_to_load() to return false if the task is frozen. This results in /proc/loadavg behavior that better meets users' expectations.

2009-04-07Fix build errors due to CONFIG_BRANCH_TRACER=yLinus Torvalds1-1/+3
The code that enables branch tracing for all (non-constant) branches plays games with the preprocessor and #define's the C 'if ()' construct to do tracing. That's all fine, but it fails for some unusual but valid C code that is sometimes used in macros, notably by the intel-iommu code: if (i=drhd->iommu, drhd->ignored) .. because now the preprocessor complains about multiple arguments to the 'if' macro. So make the macro expansion of this particularly horrid trick use varargs, and handle the case of comma-expressions in if-statements. Use another macro to do it cleanly in just one place. This replaces a patch by David (and acked by Steven) that did this all inside that one already-too-horrid macro.

2009-04-07nilfs2: support nanosecond timestampRyusuke Konishi1-4/+6
After a review of user's feedback for finding out other compatibility issues, I found nilfs improperly initializes timestamps in inode; CURRENT_TIME was used there instead of CURRENT_TIME_SEC even though nilfs didn't have nanosecond timestamps on disk. A few users gave us the report that the tar program sometimes failed to expand symbolic links on nilfs, and it turned out to be the cause. Instead of applying the above displacement, I've decided to support nanosecond timestamps on this occation. Fortunetaly, a needless 64-bit field was in the nilfs_inode struct, and I found it's available for this purpose without impact for the users. So, this will do the enhancement and resolve the tar problem.

2009-04-07nilfs2: introduce secondary super blockRyusuke Konishi1-0/+4
The former versions didn't have extra super blocks. This improves the weak point by introducing another super block at unused region in tail of the partition. This doesn't break disk format compatibility; older versions just ingore the secondary super block, and new versions just recover it if it doesn't exist. The partition created by an old mkfs may not have unused region, but in that case, the secondary super block will not be added. This doesn't make more redundant copies of the super block; it is a future work.

2009-04-07nilfs2: mark minor flag for checkpoint created by internal operationRyusuke Konishi1-0/+3
Nilfs creates checkpoints even for garbage collection or metadata updates such as checkpoint mode change. So, user often sees checkpoints created only by such internal operations. This is inconvenient in some situations. For example, application that monitors checkpoints and changes them to snapshots, will fall into an infinite loop because it cannot distinguish internally created checkpoints. This patch solves this sort of problem by adding a flag to checkpoint for identification.

2009-04-07nilfs2: clean up sketch fileRyusuke Konishi1-2/+0
The sketch file is a file to mark checkpoints with user data. It was experimentally introduced in the original implementation, and now obsolete. The file was handled differently with regular files; the file size got truncated when a checkpoint was created. This stops the special treatment and will treat it as a regular file. Most users are not affected because mkfs.nilfs2 no longer makes this file.

2009-04-07nilfs2: extend nilfs_sustat ioctl structRyusuke Konishi1-6/+4
This adds a new argument to the nilfs_sustat structure. The extended field allows to delete volatile active state of segments, which was needed to protect freshly-created segments from garbage collection but has confused code dealing with segments. This extension alleviates the mess and gives room for further simplifications. The volatile active flag is not persistent, so it's eliminable on this occasion without affecting compatibility other than the ioctl change.

2009-04-07nilfs2: remove compat ioctl codeRyusuke Konishi1-41/+0
This removes compat code from the nilfs ioctls and applies the same function for both .ioctl and .compat_ioctl file operations.

2009-04-07nilfs2: use fixed sized types for ioctl structuresRyusuke Konishi1-9/+14
Nilfs ioctl had structures not having fixed sized types such as: struct nilfs_argv { void *v_base; size_t v_nmembs; size_t v_size; int v_index; int v_flags; }; Further, some of them are wrongly aligned: e.g. struct nilfs_cpmode { __u64 cm_cno; int cm_mode; }; The size of wrongly aligned structures varies depending on architectures, and it breaks the identity of ioctl commands, which leads to arch dependent errors. Previously, these are compensated by using compat_ioctl. This fixes these problems and allows removal of compat ioctl. Since this will change sizes of those structures, binary compatibility for the past utilities will once break; new utilities have to be used instead. However, it would be helpful to avoid platform dependent problems in the long term.

2009-04-07nilfs2: remove timedwait ioctl commandRyusuke Konishi1-22/+0
This removes NILFS_IOCTL_TIMEDWAIT command from ioctl interface along with the related flags and wait queue. The command is terrible because it just sleeps in the ioctl. I prefer to avoid this by devising means of event polling in userland program. By reconsidering the userland GC daemon, I found this is possible without changing behaviour of the daemon and sacrificing efficiency.
