Pull f2fs updates from Jaegeuk Kim: "This patch-set includes the following major enhancement patches: - remount_fs callback function - restore parent inode number to enhance the fsync performance - xattr security labels - reduce the number of redundant lock/unlock data pages - avoid frequent write_inode calls The other minor bug fixes are as follows. - endian conversion bugs - various bugs in the roll-forward recovery routine" * tag 'for-f2fs-3.11' of git://git.kernel.org/pub/scm/linux/kernel/git/jaegeuk/f2fs: (56 commits) f2fs: fix to recover i_size from roll-forward f2fs: remove the unused argument "sbi" of func destroy_fsync_dnodes() f2fs: remove reusing any prefree segments f2fs: code cleanup and simplify in func {find/add}_gc_inode f2fs: optimize the init_dirty_segmap function f2fs: fix an endian conversion bug detected by sparse f2fs: fix crc endian conversion f2fs: add remount_fs callback support f2fs: recover wrong pino after checkpoint during fsync f2fs: optimize do_write_data_page() f2fs: make locate_dirty_segment() as static f2fs: remove unnecessary parameter "offset" from __add_sum_entry() f2fs: avoid freqeunt write_inode calls f2fs: optimise the truncate_data_blocks_range() range f2fs: use the F2FS specific flags in f2fs_ioctl() f2fs: sync dir->i_size with its block allocation f2fs: fix i_blocks translation on various types of files f2fs: set sb->s_fs_info before calling parse_options() f2fs: support xattr security labels f2fs: fix iget/iput of dir during recovery ...

+background_gc=%s Turn on/off cleaning operations, namely garbage

+ idle. If background_gc=on, it will turn on the garbage
+ collection and if background_gc=off, garbage collection
+ will be truned off.
+ Default value for this option is on. So garbage

discard Issue discard/TRIM commands when a segment is cleaned.
no_heap Disable heap-style segment allocation which finds free
