* btrfs: qgroup: Don't scan leaf if we're modifying reloc treeQu Wenruo2019-04-291-4/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since reloc tree doesn't contribute to qgroup numbers, just skip them. This should catch the final cause of unnecessary data ref processing when running balance of metadata with qgroups on. The 4G data 16 snapshots test (*) should explain it pretty well: | delayed subtree | refactor delayed ref | this patch --------------------------------------------------------------------- relocated | 22653 | 22673 | 22744 qgroup dirty | 122792 | 48360 | 70 time | 24.494 | 11.606 | 3.944 Finally, we're at the stage where qgroup + metadata balance cost no obvious overhead. Test environment: Test VM: - vRAM 8G - vCPU 8 - block dev vitrio-blk, 'unsafe' cache mode - host block 850evo Test workload: - Copy 4G data from /usr/ to one subvolume - Create 16 snapshots of that subvolume, and modify 3 files in each snapshot - Enable quota, rescan - Time "btrfs balance start -m" Signed-off-by: Qu Wenruo <wqu@suse.com> Signed-off-by: David Sterba <dsterba@suse.com>

| | | | | | | | | | | | | | btrfs_add_delayed_tree_ref() has a longer and longer parameter list, and some callers like btrfs_inc_extent_ref() are using @owner as level for delayed tree ref. Instead of making the parameter list longer, use btrfs_ref to refactor it, so each parameter assignment should be self-explaining without dirty level/owner trick, and provides the basis for later refactoring.

* btrfs: delayed-ref: Introduce better documented delayed ref structuresQu Wenruo2019-04-291-0/+109
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Current delayed ref interface has several problems: - Longer and longer parameter lists bytenr num_bytes parent ---------- so far so good ref_root owner offset ---------- I don't feel good now - Different interpretation of the same parameter Above @owner for data ref is inode number (u64), while for tree ref, it's level (int). They are even in different size range. For level we only need 0 ~ 8, while for ino it's BTRFS_FIRST_FREE_OBJECTID ~ BTRFS_LAST_FREE_OBJECTID. And @offset doesn't even make sense for tree ref. Such parameter reuse may look clever as an hidden union, but it destroys code readability. To solve both problems, we introduce a new structure, btrfs_ref to solve them: - Structure instead of long parameter list This makes later expansion easier, and is better documented. - Use btrfs_ref::type to distinguish data and tree ref - Use proper union to store data/tree ref specific structures. - Use separate functions to fill data/tree ref data, with a common generic function to fill common bytenr/num_bytes members. All parameters will find its place in btrfs_ref, and an extra member, @real_root, inspired by ref-verify code, is newly introduced for later qgroup code, to record which tree is triggered by this extent modification. This patch doesn't touch any code, but provides the basis for further refactoring.

* Btrfs: do not start a transaction at iterate_extent_inodes()Filipe Manana2019-04-291-6/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When finding out which inodes have references on a particular extent, done by backref.c:iterate_extent_inodes(), from the BTRFS_IOC_LOGICAL_INO (both v1 and v2) ioctl and from scrub we use the transaction join API to grab a reference on the currently running transaction, since in order to give accurate results we need to inspect the delayed references of the currently running transaction. However, if there is currently no running transaction, the join operation will create a new transaction. This is inefficient as the transaction will eventually be committed, doing unnecessary IO and introducing a potential point of failure that will lead to a transaction abort due to -ENOSPC, as recently reported [1]. That's because the join, creates the transaction but does not reserve any space, so when attempting to update the root item of the root passed to btrfs_join_transaction(), during the transaction commit, we can end up failling with -ENOSPC. Users of a join operation are supposed to actually do some filesystem changes and reserve space by some means, which is not the case of iterate_extent_inodes(), it is a read-only operation for all contextes from which it is called. The reported [1] -ENOSPC failure stack trace is the following: heisenberg kernel: ------------[ cut here ]------------ heisenberg kernel: BTRFS: Transaction aborted (error -28) heisenberg kernel: WARNING: CPU: 0 PID: 7137 at fs/btrfs/root-tree.c:136 btrfs_update_root+0x22b/0x320 [btrfs] (...) heisenberg kernel: CPU: 0 PID: 7137 Comm: btrfs-transacti Not tainted 4.19.0-4-amd64 #1 Debian 4.19.28-2 heisenberg kernel: Hardware name: FUJITSU LIFEBOOK U757/FJNB2A5, BIOS Version 1.21 03/19/2018 heisenberg kernel: RIP: 0010:btrfs_update_root+0x22b/0x320 [btrfs] (...) heisenberg kernel: RSP: 0018:ffffb5448828bd40 EFLAGS: 00010286 heisenberg kernel: RAX: 0000000000000000 RBX: ffff8ed56bccef50 RCX: 0000000000000006 heisenberg kernel: RDX: 0000000000000007 RSI: 0000000000000092 RDI: ffff8ed6bda166a0 heisenberg kernel: RBP: 00000000ffffffe4 R08: 00000000000003df R09: 0000000000000007 heisenberg kernel: R10: 0000000000000000 R11: 0000000000000001 R12: ffff8ed63396a078 heisenberg kernel: R13: ffff8ed092d7c800 R14: ffff8ed64f5db028 R15: ffff8ed6bd03d068 heisenberg kernel: FS: 0000000000000000(0000) GS:ffff8ed6bda00000(0000) knlGS:0000000000000000 heisenberg kernel: CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 heisenberg kernel: CR2: 00007f46f75f8000 CR3: 0000000310a0a002 CR4: 00000000003606f0 heisenberg kernel: DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000 heisenberg kernel: DR3: 0000000000000000 DR6: 00000000fffe0ff0 DR7: 0000000000000400 heisenberg kernel: Call Trace: heisenberg kernel: commit_fs_roots+0x166/0x1d0 [btrfs] heisenberg kernel: ? _cond_resched+0x15/0x30 heisenberg kernel: ? btrfs_run_delayed_refs+0xac/0x180 [btrfs] heisenberg kernel: btrfs_commit_transaction+0x2bd/0x870 [btrfs] heisenberg kernel: ? start_transaction+0x9d/0x3f0 [btrfs] heisenberg kernel: transaction_kthread+0x147/0x180 [btrfs] heisenberg kernel: ? btrfs_cleanup_transaction+0x530/0x530 [btrfs] heisenberg kernel: kthread+0x112/0x130 heisenberg kernel: ? kthread_bind+0x30/0x30 heisenberg kernel: ret_from_fork+0x35/0x40 heisenberg kernel: ---[ end trace 05de912e30e012d9 ]--- So fix that by using the attach API, which does not create a transaction when there is currently no running transaction.

| | | | | | | | | | | The member num_dirty_bgs of struct btrfs_transaction is not used anymore, it is set and incremented but nothing reads its value anymore. Its last read use was removed by commit 64403612b73a94 ("btrfs: rework btrfs_check_space_for_delayed_refs"). So just remove that member.
