[SCSI] mptfusion: mptctl_release is required in mptctl.c

2011-02-12T18:50:48+00:00

Added missing release callback for file_operations mptctl_fops.
Without release callback there will be never freed. It remains on
mptctl's eent list even after the file is closed and released.

Relavent RHEL bugzilla is 660871

[SCSI] mptfusion: Fix memory leak in mptctl_getiocinfo()

2011-01-24T17:42:10+00:00

A 'kfree(karg)' is missing in a failure path in
mptctl.c::mptctl_getiocinfo() which can cause a memory leak.

scsi: autoconvert trivial BKL users to private mutex

2010-09-15T19:00:45+00:00

All these files use the big kernel lock in a trivial
way to serialize their private file operations,
typically resulting from an earlier semi-automatic
pushdown from VFS.

None of these drivers appears to want to lock against
other code, and they all use the BKL as the top-level
lock in their file operations, meaning that there
is no lock-order inversion problem.

Consequently, we can remove the BKL completely,
replacing it with a per-file mutex in every case.
Using a scripted approach means we can avoid
typos.

file=$1
name=$2
if grep -q lock_kernel ${file} ; then
    if grep -q 'include.*linux.mutex.h' ${file} ; then
            sed -i '/include.*/d' ${file}
    else
            sed -i 's/include.*.*$/include /g' ${file}
    fi
    sed -i ${file} \
        -e "/^#include.*linux.mutex.h/,$ {
                1,/^\(static\|int\|long\)/ {
                     /^\(static\|int\|long\)/istatic DEFINE_MUTEX(${name}_mutex);

} }"  \
    -e "s/\(un\)*lock_kernel\>[ ]*()/mutex_\1lock(\&${name}_mutex)/g" \
    -e '/[      ]*cycle_kernel_lock();/d'
else
    sed -i -e '/include.*\/d' ${file}  \
                -e '/cycle_kernel_lock()/d'

[SCSI] mptfusion: print Doorbell register in a case of hard reset and timeout

2010-07-27T17:03:52+00:00

Printing Doorbell register in a case of hard reset and timeout
should be useful for figuring out the state of the system.

[SCSI] mptfusion: schedule_target_reset from all Reset context

2010-07-27T17:02:34+00:00

Issue:
target reset will be queued to driver's internal queue to get schedule
later. When driver add target into internal target_reset queue we will block IOs
on those target using scsi midlayer API. Now due to some cause driver is not
executing those target_reset list and it is always in block state.

Changes:
now we are clearing target_reset queue from all other Callback context
instead of only DeviceReset context.Now wherever driver is clearing
taskmgmt_in_progress flag it is considering target_reset queue cleanup
also.

[SCSI] mptfusion: Updated SCSI IO IOCTL error handling.

2010-04-11T14:24:04+00:00

Behavior changes only for IOCTLs that time out.  Current behavior of
Bus Reset remains the same for RAID Passthru Timeouts Current behavior
of Diagnostic reset for any other type of IOCTL remains the same

CHANGE: For IOCTL SCSI IOs that timeout, a Target Reset TM is sent,
instead of Bus Reset. All error handing from that point is the same as
what the driver currently does, which is to say that if the Device
Reset TM fails it escalates do diagnostic reset.
