Please, pull. Thanks.

----------------------------------------------------------------
- 6 minor cleanups found by Claude Opus 4.6
- small cleanups in dm core, dm-cache, dm-switch, dm-inlinecrypt, dm-vdo
- improve validation of metadata in dm-pcache
- dm: fix resume-vs-remove ioctl race condition
- dm: fix race condition when issuing table load ioctls concurrently
- fix dm-raid1 and dm-io, so that they work with unaligned bio vectors
- dm-integrity: use keyed markers as discard fillers
- improve metadata validation in dm-array
- fix dm-stats crash on memory allocation failure
- fix dm-dust, so that it works if it is not the first target in a table
- dm-era: fix superblock refcount leak on snapshot failure
