When we create a snapshot, we just need wait the ordered extents in the source fs/file root, but because we use the global mutex to protect this ordered extents list of the source fs/file root to avoid accessing a empty list, if someone got the mutex to access the ordered extents list of the other fs/file root, we had to wait. This patch splits the above global mutex, now every fs/file root has its own mutex to protect its own list. Signed-off-by: NMiao Xie <miaox@cn.fujitsu.com> Signed-off-by: NJosef Bacik <jbacik@fb.com>
