Looks good, you can add:

Similar to .db files, these are randomly updated extremely frequently.

Add a flag option to get xattr method that could have a bit flag of
XATTR_NOSECURITY passed to it. XATTR_NOSECURITY is generally then
set in the __vfs_getxattr path.
This handles the case of a union filesystem driver that is being
requested by the security layer to report back the xattr data.

Hi Jaegeuk,
In por_fsstress testcase, fsck reports below inconsistent status, I found one
path can cause this case.
[FIX] (fsck_chk_inode_blk:1002) --> Symlink: recover 0x1425 with i_size=4096
[ASSERT] (fsck_chk_inode_blk:1030) --> ino: 0x1425 chksum:0x6983d47, but
calculated one is: 0xdb284b35
It tries to let fsck be noticed wrong inline size, and do the fix.
