The callbacks make use of different parameters that are passed to the other type unnecessarily. This patch adds separate types for each and the unused parameters will be removed. The type extent_submit_bio_hook_t keeps all parameters and can be used where the start/done types are not appropriate. Signed-off-by: NDavid Sterba <dsterba@suse.com>

In case of raid56, writes and rebuilds always take BTRFS_STRIPE_LEN(64K) as unit, however, scrub_extent() sets blocksize as unit, so rebuild process may be triggered on every block on a same stripe. A typical example would be that when we're replacing a disappeared disk, all reads on the disks get -EIO, every block (size is 4K if blocksize is 4K) would go thru these, scrub_handle_errored_block scrub_recheck_block # re-read pages one by one scrub_recheck_block # rebuild by calling raid56_parity_recover() page by page Although with raid56 stripe cache most of reads during rebuild can be avoided, the parity recover calculation(xor or raid6 algorithms) needs to be done $(BTRFS_STRIPE_LEN / blocksize) times. This makes it smarter by doing raid56 scrub/replace on stripe length. Signed-off-by: NLiu Bo <bo.li.liu@oracle.com> Signed-off-by: NDavid Sterba <dsterba@suse.com>

Btrfs has two mount options for SSD optimizations: ssd and ssd_spread. Presently there is an option to disable all SSD optimizations, but there isn't an option to disable just ssd_spread. This patch adds a mount option nossd_spread that disables ssd_spread only.

btrfs: qgroup: Fix root item corruption when multiple same source snapshots are created with quota enabled When multiple pending snapshots referring to the same source subvolume are executed, enabled quota will cause root item corruption, where root items are using old bytenr (no backref in extent tree). This can be triggered by fstests btrfs/152. The cause is when source subvolume is still dirty, extra commit (simplied transaction commit) of qgroup_account_snapshot() can skip dirty roots not recorded in current transaction, making root item of source subvolume not updated. Fix it by forcing recording source subvolume in current transaction before qgroup sub-transaction commit.

When performing an unlock on an extent buffer we'd like to order the decrement of extent_buffer::blocking_writers with waking up any waiters. In such situations it's sufficient to use smp_mb__after_atomic rather than the heavy smp_mb. On architectures where atomic operations are fully ordered (such as x86 or s390) unconditionally executing a heavyweight smp_mb instruction causes a severe hit to performance while bringin no improvements in terms of correctness. The better thing is to use the appropriate smp_mb__after_atomic routine which will do the correct thing (invoke a full smp_mb or in the case of ordered atomics insert a compiler barrier). Put another way, an RMW atomic op + smp_load__after_atomic equals, in terms of semantics, to a full smp_mb. This ensures that none of the problems described in the accompanying comment of waitqueue_active occur. No functional changes.

The current implementation of btrfs_page_exists_in_range() gives the wrong answer if the workingset code has stored a shadow entry in the page cache.

In the last step of scrub_handle_error_block, we try to combine good copies on all possible mirrors, this works fine for raid1 and raid10, but not for raid56 as it's doing parity rebuild. If parity rebuild doesn't get back with correct data which matches its checksum, in case of replace we'd rather write what is stored in the source device than the data calculuated from parity.
