NAK. subvolumes will have to become vfsmounts sooner or later, and we
really must not support any operations spanning mountpoints.

This is a simple patch to allow reflinks to be made crossing subvolume
boundaries. The only complication I found in implementing this is that
btrfs_ioctl_clone reuses a btrfs_path. This is a slight problem because once we
allow the source and destination inodes to come from different btrfs_roots,
usrqouta is very usefull for couting (and limitng) ammount of data put
by system users. Its otherwise impossible to quicly calculate disc
usage by system users. Btrfs sould support this in future. Usrquota is
supported by ext2/ext3/reiserfs and I quess it updates its internal
database everytime fil
Some mount options are not displayed by /proc/mounts.
This patch displays the option such as compress_type by /proc/mounts.
Ex.
[before]
$ mount | grep sdc2
/dev/sdc2 on /test12 type btrfs (rw,space_cache,compress=lzo)
$ cat /proc/mounts | grep sdc2
/dev/sdc2 /test12 btrfs rw,rel
Hello,
Just found a big bug in the free space caching stuff that will result in
early ENOSPC. I'm working on fixing this bug, but it won't be until
tomorrow that I'll have it completely working, so for now make sure to
mount -o clear_cache so that it just clears the cache and doesn't use it.
- scrub commands added
- open_file_or_dir no longer static (needed by scrub.c)

This is the next patch series for scrub userland tools.
Change log v1->v2:
- commands now reachable as "btrfs scrub ..." instead of "btrfs filesystem
scrub ..."
- ability to scrub a single device instead of a whole file system
- superfluous command line options removed
- resume is now a separate

So you're trying to explicitly avoid a voluntary preemption point? Seems
like a bad idea, normally people add those :-)

When running the Linux Test Project against a BTRFS RAID 1 array,
after some time I see BTRFS trying to free an extent that still has
state [1].
Let me know if anyone is interested in a more specific reproducer and
I'll take a look.
