[PATCH v2 0/3] dm-pcache: built-in support and metadata hardening

[Li Chen <me@linux.beauty>]

From: Li Chen <chenl311@chinatelecom.cn>

This three-patch series tidies dm-pcache’s build glue and tightens the metadata scan.

Patch 1 allow dm-pcache to be linked into vmlinux and avoids clashing with the sunrpc
cache_flush() by using obj-$(CONFIG_DM_PCACHE) and renaming the helper across the tree.

Patch 2 drops a redundant recomputation of the metadata slot pointer while walking headers.

Patch 3 Ensure dm-pcache initializes cache_info from a zeroed state so metadata CRC
failures can’t leak stale flags into the new-cache path.

Thanks for your review.

Li Chen (3):
  dm-pcache: allow built-in build and rename flush helper
  dm-pcache: reuse meta_addr in pcache_meta_find_latest
  dm-pcache: zero cache_info before default init
