Merge remote-tracking branch 'linux-block/block-6.15' into xfs tree

We need two patches inside linux-block tree as dependencies of the patch
which will follow this merge.

Specifically, we need:

block: fix race between set_blocksize and read paths
block: hoist block size validation code to a separate function
