From 775bf2773858c50d2acfcdf71889984be94e7037 Mon Sep 17 00:00:00 2001 From: "Stephen M. Cameron" Date: Thu, 5 Jan 2012 10:15:31 -0600 Subject: [PATCH] [SCSI] hpsa: do not sleep in atomic context in rmmod path. Don't call kthread_stop with a spin lock held and interrupts disabled because kthread_stop will sleep waiting for the thread to stop. Signed-off-by: Stephen M.
