Allow the compiler to verify consistency of function declarations and function definitions. This patch fixes the following sparse errors: block/blk-crypto-profile.c:241:14: error: no previous prototype for ‘blk_crypto_get_keyslot’ [-Werror=missing-prototypes] 241 | blk_status_t blk_crypto_get_keyslot(struct blk_crypto_profile *profile, | ^~~~~~~~~~~~~~~~~~~~~~ block/blk-crypto-profile.c:318:6: error: no previous prototype for ‘blk_crypto_put_keyslot’ [-Werror=missing-prototypes] 318 | void blk_crypto_put_keyslot(struct blk_crypto_keyslot *slot) | ^~~~~~~~~~~~~~~~~~~~~~ block/blk-crypto-profile.c:344:6: error: no previous prototype for ‘__blk_crypto_cfg_supported’ [-Werror=missing-prototypes] 344 | bool __blk_crypto_cfg_supported(struct blk_crypto_profile *profile, | ^~~~~~~~~~~~~~~~~~~~~~~~~~ block/blk-crypto-profile.c:373:5: error: no previous prototype for ‘__blk_crypto_evict_key’ [-Werror=missing-prototypes] 373 | int __blk_crypto_evict_key(struct blk_crypto_profile *profile, | ^~~~~~~~~~~~~~~~~~~~~~ Cc: Eric Biggers <ebiggers@google.com> Signed-off-by: Bart Van Assche <bvanassche@acm.org> Link: https://lore.kernel.org/r/20221123172923.434339-1-bvanassche@acm.org Signed-off-by: Jens Axboe <axboe@kernel.dk>
Linux kernel ============ There are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. Please read Documentation/admin-guide/README.rst first. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. The formatted documentation can also be read online at: https://www.kernel.org/doc/html/latest/ There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
