scsi: flip the default on use_clustering

2018-12-19T04:13:12+00:00

Most SCSI drivers want to enable "clustering", that is merging of
segments so that they might span more than a single page.  Remove the
ENABLE_CLUSTERING define, and require drivers to explicitly set
DISABLE_CLUSTERING to disable this feature.

scsi: mvsas: fully convert to the generic DMA API

2018-10-18T01:58:52+00:00

The driver is currently using an odd mix of legacy PCI DMA API and
generic DMA API calls, switch it over to the generic API entirely.

treewide: Remove TIMER_FUNC_TYPE and TIMER_DATA_TYPE casts

2017-11-22T00:35:54+00:00

With all callbacks converted, and the timer callback prototype
switched over, the TIMER_FUNC_TYPE cast is no longer needed,
so remove it. Conversion was done with the following scripts:

    perl -pi -e 's|\(TIMER_FUNC_TYPE\)||g' \
        $(git grep TIMER_FUNC_TYPE | cut -d: -f1 | sort -u)

    perl -pi -e 's|\(TIMER_DATA_TYPE\)||g' \
        $(git grep TIMER_DATA_TYPE | cut -d: -f1 | sort -u)

The now unused macros are also dropped from include/linux/timer.h.

scsi: sas: Convert timers to use timer_setup()

2017-11-01T18:43:47+00:00

In preparation for unconditionally passing the struct timer_list pointer to
all timer callbacks, switch to using the new timer_setup() and from_timer()
to pass the timer pointer explicitly. This requires adding a pointer to
hold the timer's target task, as there isn't a link back from slow_task.

scsi: libsas: move bus_reset_handler() to target_reset_handler()

2017-08-25T21:21:10+00:00

The bus reset handler is calling I_T Nexus reset, which logically is a
target reset as it need to specify both the initiator and the target.
So move it to target reset.

scsi: mvsas: replace kfree with scsi_host_put

2017-08-10T23:55:35+00:00

The return value of scsi_host_alloc() should be released by
scsi_host_put(). However, in function mvs_pci_init(), kfree()
is used. This patch replaces kfree() with scsi_host_put() to avoid
possible memory leaks.
