Subject: [PATCH v2 0/2] fscrypt: rework filesystem-level keyring

This series reworks the filesystem-level keyring to not use the keyrings
subsystem as part of its internal implementation (except for ->mk_users,
which remains unchanged for now).  This fixes several issues, described
in the first patch.  This is also a prerequisite for removing the direct
use of struct request_queue from filesystem code, as discussed at
https://lore.kernel.org/linux-fscrypt/20220721125929.1866403-1-hch@lst.de/T/#u

Changed v1 => v2:
    - Don't compare uninitialized bytes of struct fscrypt_key_specifier
    - Don't use refcount_dec_and_lock() unnecessarily
    - Other minor cleanups

Eric Biggers (2):
  fscrypt: stop using keyrings subsystem for fscrypt_master_key
  fscrypt: stop holding extra request_queue references
