[f2fs-dev] [PATCH 3/3] f2fs/020: do sanity check on i_xattr_nid

[Chao Yu via Linux-f2fs-devel <linux-f2fs-devel@lists.sourceforge.net>]

This is a regression test:
1. create directory
2. add a new xattr entry to create xattr node
3. use inject.f2fs to inject nid of xattr node w/ ino in a file
4. check whether f2fs kernel module will detect and report such
   corruption in the file
