From 24430458bb924e371ff894e26bfa9f73707f53fb Mon Sep 17 00:00:00 2001 From: Jeff Garzik Date: Fri, 27 Jul 2007 13:00:48 -0400 Subject: [SCSI] arcmsr: Fix hardware wait loops Remove _interruptible, since receiving a signal while waiting on a hardware condition will simply cause the driver to busy-wait. Using msleep_interruptible() is rarely the right thing to do, when waiting on a hardware condition to change. Also, replace msleep with ssleep while doing this, where appropriate.
