Ian Campbell 4c31a78114 xenbus: do not hold transaction_mutex when returning to userspace ... ================================================ [ BUG: lock held when returning to user space! ] ------------------------------------------------ xenstore-list/3522 is leaving the kernel with locks still held! 1 lock held by xenstore-list/3522: #0: (&xs_state.transaction_mutex){......}, at: [<c026dc6f>] xenbus_dev_request_and_reply+0x8f/0xa0 The canonical fix for this type of issue appears to be to maintain a count manually rather than using an rwsem so do that here.
