Subject: [PATCH 0/5] ext4: inline data cleanup

This series starts some cleanup of the inline data support, making it
easier to handle cases where the disk data is changed underneath the
system.

They were tested with some test cases that have good coverage with both
regular files and directories (indexed and not).

A few syzkaller or hand-written reproducers have also been tested and shown
not to crash the system anymore, but mount the filesystem read-only,
failing with -EUCLEAN.

Thadeu Lima de Souza Cascardo (5):
  ext4: inline: remove extra size check when writing data
  ext4: inline: use cached i_inline_size instead of e_value_size
  ext4: introduce wrapper to read data from inode
  ext4: add a wrapper to update i_inline_off and i_inline_size
  ext4: make i_inline_off point to data
