James Bottomley 559b3bbfa9 locking/percpu-rwsem: add freezable alternative to down_read ... Percpu-rwsems are used for superblock locking. However, we know the read percpu-rwsem we take for sb_start_write() on a frozen filesystem needs not to inhibit system from suspending or hibernating. That means it needs to wait with TASK_UNINTERRUPTIBLE | TASK_FREEZABLE. Introduce a new percpu_down_read_freezable() that allows us to control whether TASK_FREEZABLE is added to the wait flags.
