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 fs/crypto/fscrypt_private.h | 74 ++++-- fs/crypto/hooks.c | 10 +- fs/crypto/inline_crypt.c | 83 +++--- fs/crypto/keyring.c | 495 +++++++++++++++++++----------------- fs/crypto/keysetup.c | 89 +++---- fs/crypto/keysetup_v1.c | 4 +- fs/crypto/policy.c | 8 +- fs/super.c | 2 +- include/linux/fs.h | 2 +- include/linux/fscrypt.h | 4 +- 10 files changed, 406 insertions(+), 365 deletions(-) base-commit: 568035b01cfb107af8d2e4bd2fb9aea22cf5b868 Signed-off-by: Christoph Hellwig
