Subject: [PATCH v2 0/2] ext4, f2fs: stop using PG_error for fscrypt and fsverity

This series changes ext4 and f2fs to stop using PG_error to track
decryption and verity errors.  This is a step towards freeing up
PG_error for other uses, as discussed at

Note: due to the interdependencies with fs/crypto/ and fs/verity/,
I couldn't split this up into separate patches for each filesystem.
I'd appreciate Acks from the ext4 and f2fs maintainers so that I can
take these patches.  Otherwise I'm not sure how to move them forward.

Changed v1 => v2:
   - Rebased onto v6.0-rc1 and resolved conflicts in f2fs.

Eric Biggers (2):
  fscrypt: stop using PG_error to track error status
  fsverity: stop using PG_error to track error status
