Merge tag 'for-f2fs-3.12' of git://git.kernel.org/pub/scm/linux/kernel/git/jaegeuk/f2fs
Pull f2fs updates from Jaegeuk Kim: "This patch-set includes the following major enhancement patches: - support inline xattrs - add sysfs support to control GCs explicitly - add proc entry to show the current segment usage information - improve the GC/SSR performance The other bug fixes are as follows: - avoid the overflow on status calculation - fix some error handling routines - fix inconsistent xattr states after power-off-recovery - fix incorrect xattr node offset definition - fix deadlock condition in fsync - fix the fdatasync routine for power-off-recovery" * tag 'for-f2fs-3.12' of git://git.kernel.org/pub/scm/linux/kernel/git/jaegeuk/f2fs: (40 commits) f2fs: optimize gc for better performance f2fs: merge more bios of node block writes f2fs: avoid an overflow during utilization calculation f2fs: trigger GC when there are prefree segments f2fs: use strncasecmp() simplify the string comparison f2fs: fix omitting to update inode page f2fs: support the inline xattrs f2fs: add the truncate_xattr_node function f2fs: introduce __find_xattr for readability f2fs: reserve the xattr space dynamically f2fs: add flags for inline xattrs f2fs: fix error return code in init_f2fs_fs() f2fs: fix wrong BUG_ON condition f2fs: fix memory leak when init f2fs filesystem fail f2fs: fix a compound statement label error f2fs: avoid writing inode redundantly when creating a file f2fs: alloc_page() doesn't return an ERR_PTR f2fs: should cover i_xattr_nid with its xattr node page lock f2fs: check the free space first in new_node_page f2fs: clean up the needless end 'return' of void function ...
