2011-04-05UBIFS: fix error path in dbg_debugfs_init_fsArtem Bityutskiy1-5/+5
The debug interface is substandard and on error returns either NULL or an error code packed in the pointer. So using "IS_ERR" for the pointers returned by debugfs function is incorrect. Instead, we should use IS_ERR_OR_NULL. This path is an improved vestion of the original patch from Phil Carmody.

2011-04-05UBIFS: unify error path dbg_debugfs_init_fsArtem Bityutskiy1-8/+6
This is just a small clean-up patch which simlifies and unifies the error path in the dbg_debugfs_init_fs(). We have common error path for all failure cases in this function except of the very first case. And this patch makes the first failure case use the same error path as the other cases by using the 'fname' and 'dent' variables.

2011-04-05UBIFS: do not select KALLSYMS_ALLArtem Bityutskiy1-1/+1
All UBIFS needs is to make sure we stacktraces when UBIFS debugging is enabled. It is enough to select KALLSYMS for this, KALLSYMS_ALL is not necessary. Moreover, Randy Dunlap reported that UBIFS causes the following Kconfig dependency warning: warning: (UBIFS_FS_DEBUG && LOCKDEP && LATENCYTOP) selects KALLSYMS_ALL which has unmet direct dependencies (DEBUG_KERNEL && KALLSYMS) The reason is that KALLSYMS_ALL requires DEBUG_KERNEL and KALLSYMS, so ideally, to select KALLSYMS_ALL we'd need to select DEBUG_KERNEL and KALLSYMS first. This seems to be too much to select. The easiest way to go is to forget about KALLSYMS_ALL and just select KALLSYMS when UBIFS debugging is enabled - that should be enough for stackdumps.

While re-mounting, we write to the media, but we still have the c->ro_mount flag set. The fix is very simple - just clear the flag before starting re-mounting R/W. These warnings are caused by the following commit: 2ef13294d29bcfb306e0d360f1b97f37b647b0c0 For -stable guys: this bug was introduced in 2.6.38, this is materieal for 2.6.38-stable.

2011-04-05UBIFS: do not read flash unnecessarilyArtem Bityutskiy1-1/+1
This fix makes the 'dbg_check_old_index()' function return immediately if debugging is disabled, instead of executing incorrect 'goto out' which causes UBIFS to: 1. Allocate memory 2. Read the flash On every commit. OK, we do not commit that often, but it is still silly to do unneeded I/O anyway. Credits to coverity for spotting this silly issue.

Commit b3df895aebe091b1657 "powerpc/kexec: Add support for FSL-BookE" introduced the original PPC_STD_MMU_64 checks around the function crash_kexec_wait_realmode(). Then commit c2be05481f61252 "powerpc: Fix default_machine_crash_shutdown #ifdef botch" changed the ifdef around the calling site to add a check on SMP, but the ifdef around the function itself was left unchanged, leaving an unused function for PPC_STD_MMU_64=y and SMP=n Rather than have two ifdefs that can get out of sync like this, simply put the corrected conditional around the function and use a stub to get rid of one set of ifdefs completely.

2011-04-05Btrfs: don't warn in btrfs_add_orphanJosef Bacik1-2/+0
When I moved the orphan adding to btrfs_truncate I missed the fact that during orphan cleanup we just add the orphan items to the orphan list without going through btrfs_orphan_add, which results in lots of warnings on mount if you have any orphan items that need to be truncated. Just remove this warning since it's ok, this will allow all of the normal space accounting take place.

2011-04-05Btrfs: fix free space cache when there are pinned extents and clusters V2Josef Bacik1-4/+78
I noticed a huge problem with the free space cache that was presenting as an early ENOSPC. Turns out when writing the free space cache out I forgot to take into account pinned extents and more importantly clusters. This would result in us leaking free space everytime we unmounted the filesystem and remounted it. I fix this by making sure to check and see if the current block group has a cluster and writing out any entries that are in the cluster to the cache, as well as writing any pinned extents we currently have to the cache since those will be available for us to use the next time the fs mounts. This patch also adds a check to the end of load_free_space_cache to make sure we got the right amount of free space cache, and if not make sure to clear the cache and re-cache the old fashioned way.

2011-04-05Btrfs: Fix uninitialized root flags for subvolumesLi Zefan5-1/+30
root_item->flags and root_item->byte_limit are not initialized when a subvolume is created. This bug is not revealed until we added readonly snapshot support - now you mount a btrfs filesystem and you may find the subvolumes in it are readonly. To work around this problem, we steal a bit from root_item->inode_item->flags, and use it to indicate if those fields have been properly initialized. When we read a tree root from disk, we check if the bit is set, and if not we'll set the flag and initialize the two fields of the root item.
