udf: Fix lock ordering in udf_evict_inode()

2024-06-05T08:36:46Z

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.

udf: Drop pointless IS_IMMUTABLE and IS_APPEND check

2024-06-05T08:36:46Z

udf_setsize() checks for IS_IMMUTABLE and IS_APPEND flags. This is however pointless as UDF does not have capability to store these flags and never allows to set them. Furthermore this is the only place in UDF code that was actually checking these flags. Remove the pointless check. Signed-off-by: Jan Kara

udf: Remove GFP_NOFS allocation in udf_expand_file_adinicb()

2024-01-23T18:21:10Z

udf_expand_file_adinicb() is called under inode->i_rwsem and mapping->invalidate_lock. i_rwsem is safe wrt fs reclaim, invalidate_lock on this inode is safe as well (we hold inode reference so reclaim will not touch it, furthermore even lockdep should not complain as invalidate_lock is acquired from udf_evict_inode() only when truncating inode which should not happen from fs reclaim).
