fs: convert block_commit_write() to take a folio

2025-03-17T05:06:22+00:00

All callers now have a folio, so pass it in instead of converting folio->page->folio. Link: https://lkml.kernel.org/r/20250217192009.437916-1-willy@infradead.org Signed-off-by: Matthew Wilcox (Oracle) Signed-off-by: Andrew Morton

udf: Fix lock ordering in udf_evict_inode()

2024-06-05T08:36:46+00:00

udf_evict_inode() calls udf_setsize() to truncate deleted inode. However inode deletion through udf_evict_inode() can happen from inode reclaim context and udf_setsize() grabs mapping->invalidate_lock which isn't generally safe to acquire from fs reclaim context since we allocate pages under mapping->invalidate_lock for example in a page fault path. This is however not a real deadlock possibility as by the time udf_evict_inode() is called, nobody can be accessing the inode, even less work with its page cache. So this is just a lockdep triggering false positive. Fix the problem by moving mapping->invalidate_lock locking outsize of udf_setsize() into udf_setattr() as grabbing mapping->invalidate_lock from udf_evict_inode() is pointless.
