udf: Fix data integrity writeout issues

2026-07-27T14:25:32+00:00

UDF could fail to properly write out inode on fsync(2) due to races with WB_SYNC_NONE writeback. Several racing fsyncs could also result in some fsync returning earlier than all metadata buffers were properly persisted. Fix all these issues by using new .sync_inode_metadata method which makes sure all inode related metadata is written to disk during any WB_SYNC_ALL writeback.

udf: Switch to generic_buffers_fsync()

2026-03-26T14:03:27+00:00

UDF uses metadata bh list attached to inode. Switch it to generic_buffers_fsync() instead of generic_file_fsync() as we'll be removing metadata bh handling from generic_file_fsync().

udf: add setlease file operation

2026-01-12T09:55:47+00:00

Add the setlease file_operation pointing to generic_setlease to the udf file_operations structures. A future patch will change the default behavior to reject lease attempts with -EINVAL when there is no setlease file operation defined. Add generic_setlease to retain the ability to set leases on this filesystem.

udf: Remove GFP_NOFS from dir iteration code

2024-01-23T18:21:10+00:00

Directory iteration code was using GFP_NOFS allocations in two places. However the code is called only under inode->i_rwsem which is generally safe wrt reclaim. So we can do the allocations with GFP_KERNEL instead. Signed-off-by: Jan Kara

udf: replace ll_rw_block()

2022-09-12T03:26:07+00:00

ll_rw_block() is not safe for the sync read path because it cannot guarantee that submitting read IO if the buffer has been locked. We could get false positive EIO after wait_on_buffer() if the buffer has been locked by others. So stop using ll_rw_block(). We also switch to new bh_readahead_batch() helper for the buffer array readahead path.

fs/buffer: Combine two submit_bh() and ll_rw_block() arguments

2022-07-14T18:14:32+00:00

Both submit_bh() and ll_rw_block() accept a request operation type and request flags as their first two arguments. Micro-optimize these two functions by combining these first two arguments into a single argument. This patch does not change the behavior of any of the modified code.
