| H A D | blk-crypto-internal.h | diff 93f221ae08381e994ac9f9ff6aa743e612e49718 Tue Sep 15 22:53:14 CDT 2020 Eric Biggers <ebiggers@google.com> block: make blk_crypto_rq_bio_prep() able to fail
blk_crypto_rq_bio_prep() assumes its gfp_mask argument always includes
__GFP_DIRECT_RECLAIM, so that the mempool_alloc() will always succeed.
However, blk_crypto_rq_bio_prep() might be called with GFP_ATOMIC via
setup_clone() in drivers/md/dm-rq.c.
This case isn't currently reachable with a bio that actually has an
encryption context. However, it's fragile to rely on this. Just make
blk_crypto_rq_bio_prep() able to fail.
