2013-01-03Drivers: scsi: remove __dev* attributes.Greg Kroah-Hartman2-7/+7
CONFIG_HOTPLUG is going away as an option. As a result, the __dev* markings need to be removed. This change removes the use of __devinit, __devexit_p, __devinitdata, __devinitconst, and __devexit from these drivers. Based on patches originally written by Bill Pemberton, but redone by me in order to handle some of the coding style issues better, by hand.

2012-12-04megaraid: fix BUG_ON() from incorrect use of delayed workXiaotian Feng2-9/+7
megaraid use INIT_WORK to declare a hotplug_work, but cast the hotplug_work from work_struct to delayed_work and schedule_delayed_work on it. This is very dangerous, as other part of delayed_work might be kernel memories allocated by others. With commit 8852aac ("workqueue: mod_delayed_work_on() shouldn't queue timer on 0 delay"), schedule_delayed_work() will check dwork->timer before queue_work even when @delay is 0, this causes megaraid code to hit the BUG_ON() in workqueue code. Change megaraid code to use delayed work. Signed-off-by: Xiaotian Feng <dannyfeng@tencent.com> Signed-off-by: Tejun Heo <tj@kernel.org> Cc: Neela Syam Kolli <megaraidlinux@lsi.com> Cc: "James E.J.

2011-10-20[SCSI] megaraid_sas: Fix instance access in megasas_reset_timeradam radford1-2/+1
The following patch for megaraid_sas will fix a potential bad pointer access in megasas_reset_timer(), when a MegaRAID 9265/9285 or 9360/9380 gets a timeout. megasas_build_io_fusion() sets SCp.ptr to be a struct megasas_cmd_fusion *, but then megasas_reset_timer() was casting SCp.ptr to be a struct megasas_cmd *, then trying to access cmd->instance, which is invalid. Just loading instance from scmd->device->host->hostdata in megasas_reset_timer() fixes the issue.
