[PATCH v3 0/3] fscrypt: rework keyring and stop using request_queue

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Patch 1 of this series reworks the fscrypt 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 patch itself.  This is also a
prerequisite for eliminating the direct use of struct request_queue from
filesystem code, as discussed at
https://lore.kernel.org/linux-fscrypt/20220721125929.1866403-1-hch@xxxxxx/T/#u

Patches 2-3 eliminate the direct uses of struct request_queue from
fs/crypto/ that don't require block layer changes.  (The remaining uses
will be eliminated later by changing some of the blk-crypto functions.)

Changed in v3:
    - Added patch "fscrypt: work on block_devices instead of request_queues"

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

Christoph Hellwig (1):
  fscrypt: work on block_devices instead of request_queues

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