If the transaction handle doesn't have used blocks but has created new block groups make sure we turn the fs into readonly mode too. This is because the new block groups didn't get all their metadata persisted into the chunk and device trees, and therefore if a subsequent transaction starts, allocates space from the new block groups, writes data or metadata into that space, commits successfully and then after we unmount and mount the filesystem again, the same space can be allocated again for a new block group, resulting in file data or metadata corruption. Example where we don't abort the transaction when we fail to finish the chunk allocation (add items to the chunk and device trees) and later a future transaction where the block group is removed fails because it can't find the chunk item in the chunk tree: [25230.404300] WARNING: CPU: 0 PID: 7721 at fs/btrfs/super.c:260 __btrfs_abort_transaction+0x50/0xfc [btrfs]() [25230.404301] BTRFS: Transaction aborted (error -28) [25230.404302] Modules linked in: btrfs dm_flakey nls_utf8 fuse xor raid6_pq ntfs vfat msdos fat xfs crc32c_generic libcrc32c ext3 jbd ext2 dm_mod nfsd auth_rpcgss oid_registry nfs_acl nfs lockd fscache sunrpc loop psmouse i2c_piix4 i2ccore parport_pc parport processor button pcspkr serio_raw thermal_sys evdev microcode ext4 crc16 jbd2 mbcache sr_mod cdrom ata_generic sg sd_mod crc_t10dif crct10dif_generic crct10dif_common virtio_scsi floppy e1000 ata_piix libata virtio_pci virtio_ring scsi_mod virtio [last unloaded: btrfs] [25230.404325] CPU: 0 PID: 7721 Comm: xfs_io Not tainted 3.17.0-rc5-btrfs-next-1+ #1 [25230.404326] Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS rel-1.7.5-0-ge51488c-20140602_164612-nilsson.home.kraxel.org 04/01/2014 [25230.404328] 0000000000000000 ffff88004581bb08 ffffffff813e7a13 ffff88004581bb50 [25230.404330] ffff88004581bb40 ffffffff810423aa ffffffffa049386a 00000000ffffffe4 [25230.404332] ffffffffa05214c0 000000000000240c ffff88010fc8f800 ffff88004581bba8 [25230.404334] Call Trace: [25230.404338] [<ffffffff813e7a13>] dump_stack+0x45/0x56 [25230.404342] [<ffffffff810423aa>] warn_slowpath_common+0x7f/0x98 [25230.404351] [<ffffffffa049386a>] ? __btrfs_abort_transaction+0x50/0xfc [btrfs] [25230.404353] [<ffffffff8104240b>] warn_slowpath_fmt+0x48/0x50 [25230.404362] [<ffffffffa049386a>] __btrfs_abort_transaction+0x50/0xfc [btrfs] [25230.404374] [<ffffffffa04a8c43>] btrfs_create_pending_block_groups+0x10c/0x135 [btrfs] [25230.404387] [<ffffffffa04b77fd>] __btrfs_end_transaction+0x7e/0x2de [btrfs] [25230.404398] [<ffffffffa04b7a6d>] btrfs_end_transaction+0x10/0x12 [btrfs] [25230.404408] [<ffffffffa04a3d64>] btrfs_check_data_free_space+0x111/0x1f0 [btrfs] [25230.404421] [<ffffffffa04c53bd>] __btrfs_buffered_write+0x160/0x48d [btrfs] [25230.404425] [<ffffffff811a9268>] ? cap_inode_need_killpriv+0x2d/0x37 [25230.404429] [<ffffffff810f6501>] ? get_page+0x1a/0x2b [25230.404441] [<ffffffffa04c7c95>] btrfs_file_write_iter+0x321/0x42f [btrfs] [25230.404443] [<ffffffff8110f5d9>] ? handle_mm_fault+0x7f3/0x846 [25230.404446] [<ffffffff813e98c5>] ? mutex_unlock+0x16/0x18 [25230.404449] [<ffffffff81138d68>] new_sync_write+0x7c/0xa0 [25230.404450] [<ffffffff81139401>] vfs_write+0xb0/0x112 [25230.404452] [<ffffffff81139c9d>] SyS_pwrite64+0x66/0x84 [25230.404454] [<ffffffff813ebf52>] system_call_fastpath+0x16/0x1b [25230.404455] ---[ end trace 5aa5684fdf47ab38 ]--- [25230.404458] BTRFS warning (device sdc): btrfs_create_pending_block_groups:9228: Aborting unused transaction(No space left).

Our gluster boxes get several thousand statfs() calls per second, which begins to suck hardcore with all of the lock contention on the chunk mutex and dev list mutex. We don't really need to hold these things, if we have transient weirdness with statfs() because of the chunk allocator we don't care, so remove this locking. We still need the dev_list lock if you mount with -o alloc_start however, which is a good argument for nuking that thing from orbit, but that's a patch for another day.

[BUG] Originally when mount btrfs with "-o subvol=" mount option, btrfs will lose all security lable. And if the btrfs fs is mounted somewhere else, due to the lost of security lable, SELinux will refuse to mount since the same super block is being mounted using different security lable. [REPRODUCER] With SELinux enabled: #mkfs -t btrfs /dev/sda5 #mount -o context=system_u:object_r:nfs_t:s0 /dev/sda5 /mnt/btrfs #btrfs subvolume create /mnt/btrfs/subvol #mount -o subvol=subvol,context=system_u:object_r:nfs_t:s0 /dev/sda5 /mnt/test kernel message: SELinux: mount invalid. Same superblock, different security settings for (dev sda5, type btrfs) [REASON] This happens because btrfs will call vfs_kern_mount() and then mount_subtree() to handle subvolume name lookup. First mount will cut off all the security lables and when it comes to the second vfs_kern_mount(), it has no security label now. [FIX] This patch will makes btrfs behavior much more like nfs, which has the type flag FS_BINARY_MOUNTDATA, making btrfs handles the security label internally. So security label will be set in the real mount time and won't lose label when use with "subvol=" mount option.

This has been discussed in thread: http://thread.gmane.org/gmane.comp.file-systems.btrfs/32528 and this patch implements this proposal: http://thread.gmane.org/gmane.comp.file-systems.btrfs/32536 Works fine for "clean" raid profiles where the raid factor correction does the right job. Otherwise it's pessimistic and may show low space although there's still some left. The df nubmers are lightly wrong in case of mixed block groups, but this is not a major usecase and can be addressed later. The RAID56 numbers are wrong almost the same way as before and will be addressed separately.

There are a few d_obtain_alias callers that are using it to get the root of a filesystem which may already have an alias somewhere else. This is not the same as the filehandle-lookup case, and none of them actually need DCACHE_DISCONNECTED set. It isn't really a serious problem, but it would really be clearer if we reserved DCACHE_DISCONNECTED for those cases where it's actually needed. In the btrfs case this was causing a spurious printk from nfsd/nfsfh.c:fh_verify when it found an unexpected DCACHE_DISCONNECTED dentry. Josef worked around this by unsetting DCACHE_DISCONNECTED manually in 3a0dfa6a "Btrfs: unset DCACHE_DISCONNECTED when mounting default subvol", and this replaces that workaround.

Before applying this patch, the task had to reclaim the metadata space by itself if the metadata space was not enough. And When the task started the space reclamation, all the other tasks which wanted to reserve the metadata space were blocked. At some cases, they would be blocked for a long time, it made the performance fluctuate wildly. So we introduce the background metadata space reclamation, when the space is about to be exhausted, we insert a reclaim work into the workqueue, the worker of the workqueue helps us to reclaim the reserved space at the background. By this way, the tasks needn't reclaim the space by themselves at most cases, and even if the tasks have to reclaim the space or are blocked for the space reclamation, they will get enough space more quickly.

Previously, the no-op "mount -o mount /dev/xxx" operation when the file system is already mounted read-write causes an implied, unconditional syncfs(). This seems pretty stupid, and it's certainly documented or guaraunteed to do this, nor is it particularly useful, except in the case where the file system was mounted rw and is getting remounted read-only. However, it's possible that there might be some file systems that are actually depending on this behavior. In most file systems, it's probably fine to only call sync_filesystem() when transitioning from read-write to read-only, and there are some file systems where this is not needed at all (for example, for a pseudo-filesystem or something like romfs).

Now that we can adjust the commit interval with a remount, we need to wake up the transaction thread or else he will continue to sleep until the previous transaction interval has elapsed before waking up. So, if we go from a large commit interval to something smaller, the transaction thread will not wake up until the large interval has expired. This also causes the cleaner thread to stay sleeping, since it gets woken up by the transaction thread. Fix it by simply waking up the transaction thread during a remount.
