btrfs: sysfs: add per-fs attribute for read policy
Add
/sys/fs/btrfs/UUID/read_policy
attribute so that the read policy for the raid1, raid1c34 and raid10 can
be tuned.
When this attribute is read, it will show all available policies, with
active policy in [ ]. The read_policy attribute can be written using one
of the items listed in there.
For example:
$ cat /sys/fs/btrfs/UUID/read_policy
[pid]
$ echo pid > /sys/fs/btrfs/UUID/read_policy
