Subject: [PATCH 0/4] ext4: avoid OOB when system.data xattr changes underneath the filesystem

This patchset changes some of the error paths involving dir entries lookups
and recheck that xattrs are valid after an inode is potentially reread from
disk.

Thadeu Lima de Souza Cascardo (4):
  ext4: ext4_search_dir should return a proper error
  ext4: return error on ext4_find_inline_entry
  ext4: explicitly exit when ext4_find_inline_entry returns an error
  ext4: avoid OOB when system.data xattr changes underneath the
    filesystem
