f2fs: support plain user/group quota
This patch adds to support plain user/group quota.
Change Note by Jaegeuk Kim.
- Use f2fs page cache for quota files in order to consider garbage collection.
so, quota files are not tolerable for sudden power-cuts, so user needs to do
quotacheck.
- setattr() calls dquot_transfer which will transfer inode->i_blocks.
We can't reclaim that during f2fs_evict_inode(). So, we need to count
node blocks as well in order to match i_blocks with dquot's space.
Note that, Chao wrote a patch to count inode->i_blocks without inode block.
(f2fs: don't count inode block in in-memory inode.i_blocks)
- in f2fs_remount, we need to make RW in prior to dquot_resume.
- handle fault_injection case during f2fs_quota_off_umount
- TODO: Project quota
