Merge branch 'for-linus' of git://git.kernel.dk/linux-block
Pull block layer fixes from Jens Axboe:
"Two smaller fixes for this cycle:
- A fixup from Keith so that NVMe compiles without BLK_INTEGRITY,
basically just moving the code around appropriately.
- A fixup for shm, fixing an oops in shmem_mapping() for mapping with
no inode. From Sasha"
[ The shmem fix doesn't look block-layer-related, but fixes a bug that
happened due to the backing_dev_info removal.. - Linus ]
* 'for-linus' of git://git.kernel.dk/linux-block:
mm: shmem: check for mapping owner before dereferencing
NVMe: Fix for BLK_DEV_INTEGRITY not set
