Date: Tue, 26 Jan 2010 15:34:00 -0800 From: Greg KH <gregkh@...e.de> To: linux-kernel@...r.kernel.org, stable@...nel.org Cc: stable-review@...nel.org, torvalds@...ux-foundation.org, akpm@...ux-foundation.org, alan@...rguk.ukuu.org.uk, Mike Christie <michaelc@...wisc.edu>, James Bottomley <James.Bottomley@...e.de> Subject: [34/98] [SCSI] iscsi class: modify handling of replacement timeout 2.6.32-stable review patch. If anyone has any objections, please let us know. ------------------ From: Mike Christie <michaelc@...wisc.edu> commit fdd46dcbe4468a1f47a2cc9be442d11c3d21dd68 upstream. This patch modifies the replacement/recovery_timeout so it works more like the fc fast io fail tmo. If userspace tries to set the replacement/recovery_timeout to less than zero, we will turn off the forced recovery cleanup. If userspace sets the value to 0 then we will force the recovery cleanup immediately.
