Revision c331eb04b995ad276a7ece4608326f1db4e137d8 authored by NeilBrown on 31 May 2006, 04:27:13 UTC, committed by Linus Torvalds on 31 May 2006, 23:27:11 UTC
From: NeilBrown <neilb@suse.de> If an error is reported by a drive in a RAID array (which is done via bi_end_io - in interrupt context), we call md_error and md_new_event which calls sysfs_notify. However sysfs_notify grabs a mutex and so cannot be called in interrupt context. This patch just creates a variant of md_new_event which avoids the sysfs call, and uses that. A better fix for later is to arrange for the event to be called from user-context. Note: avoiding the sysfs call isn't a problem as an error will not, by itself, modify the sync_action attribute. (We do still need to wake_up(&md_event_waiters) as an error by itself will modify /proc/mdstat).
