NAK. subvolumes will have to become vfsmounts sooner or later, and we

We create two subvolumes (meego_root and meego_home) in
btrfs root directory. And set meego_root as default mount
subvolume. After we remount btrfs, meego_root is mounted
to top directory by default. Then when we try to mount
meego_home (subvol=meego_home) to a subdirectory, it failed.
The problem

the object id of the space cache inode's key is allocated from the relative
root, just like the regular file. So we can't identify space cache inode by
checking the object id of the inode's key, and we have to clear __GFP_FS flag
at the time we look up the

There should be a way to make automatic checkpoints less frequent. On
the busy ssd I have about 7 cp every second. If it were for example
once every 5 minutes then one could set garbage removal every few
days.
Also garbage removal should have option to clean only if like 90% of
drive is used.

I noticed a huge problem with the free space cache that was presenting as an
early ENOSPC. Turns out when writing the free space cache out I forgot to take
into account pinned extents and more importantly clusters. This would result in
us leaking free space everytime we unmounted the filesystem

Frankly I see no point extending the ioctl interface when we have
a syscall interface.

I'd even go so far as to say we could probably axe the xfs and ocfs2 ioctls
since we have the fallocate interface :). Thanks,
