fsverity: remove inode from fsverity_verification_ctx (2026-02-04 11:31:54
-0800)
----------------------------------------------------------------
fsverity cleanups, speedup, and memory usage optimization from
Christoph Hellwig:
- Move some logic into common code
- Fix btrfs to reject truncates of fsverity files
- Improve the Merkle tree readahead implementation
- Store each inode's fsverity_info in a hash table instead of using a
pointer in the filesystem-specific part of the inode.
This optimizes for memory usage in the usual case where most files
don't have fsverity enabled.
- Look up the fsverity_info fewer times during verification, to
amortize the hash table overhead
----------------------------------------------------------------
Christoph Hellwig (17):
fs,fsverity: reject size changes on fsverity files in setattr_prepare
fs,fsverity: clear out fsverity_info from common code
ext4: don't build the fsverity work handler for !CONFIG_FS_VERITY
f2fs: don't build the fsverity work handler for !CONFIG_FS_VERITY
fsverity: pass struct file to ->write_merkle_tree_block
fsverity: start consolidating pagecache code
fsverity: don't issue readahead for non-ENOENT errors from
__filemap_get_folio
readahead: push invalidate_lock out of page_cache_ra_unbounded
ext4: move ->read_folio and ->readahead to readpage.c
fsverity: kick off hash readahead at data I/O submission time
fsverity: deconstify the inode pointer in struct fsverity_info
fsverity: push out fsverity_info lookup
fs: consolidate fsverity_info lookup in buffer.c
ext4: consolidate fsverity_info lookup
f2fs: consolidate fsverity_info lookup
btrfs: consolidate fsverity_info lookup
fsverity: use a hashtable to find the fsverity_info
