Previously, f2fs_setxattr assigns i_xattr_nid in the inode page inconsistently.
The scenario is:
= Thread 1 = = Thread 2 = = fi->i_xattr_nid = = on-disk nid =
f2fs_setxattr 0 0
new_node_page X 0
sync_inode_page X X
checkpoint X X -.
grab_cache_page X X |
--> allocate a new xattr node block or -ENOSPC <----------------'
At this moment, the checkpoint stores inconsistent data where the inode has
i_xattr_nid but actual xattr node block is not allocated yet.
So, we should assign the real i_xattr_nid only after its xattr node block is
allocated.
