Thomas Bertschinger 97a0b5be50 Add mutex_enter_interruptible() for interruptible sleeping IOCTLs ... Many long-running ZFS ioctls lock the spa_namespace_lock, forcing concurrent ioctls to sleep for the mutex. Previously, the only option is to call mutex_enter() which sleeps uninterruptibly. This is a usability issue for sysadmins, for example, if the admin runs `zpool status` while a slow `zpool import` is ongoing, the admin's shell will be locked in uninterruptible sleep for a long time. This patch resolves this admin usability issue by introducing mutex_enter_interruptible() which sleeps interruptibly while waiting to acquire a lock. It is implemented for both Linux and FreeBSD. The ZFS_IOC_POOL_CONFIGS ioctl, used by `zpool status`, is changed to use this new macro so that the command can be interrupted if it is issued during a concurrent `zpool import` (or other long-running operation).
