2006-03-26[PATCH] mempool: use mempool_create_slab_pool()Matthew Dobson
Modify well over a dozen mempool users to call mempool_create_slab_pool() rather than calling mempool_create() with extra arguments, saving about 30 lines of code and increasing readability.

2006-03-26[PATCH] mempool: use common mempool kmalloc allocatorMatthew Dobson
This patch changes several mempool users, all of which are basically just wrappers around kmalloc(), to use the common mempool_kmalloc/kfree, rather than their own wrapper function, removing a bunch of duplicated code.

2006-03-24[PATCH] Make libata not powerdown drivers on PM_EVENT_FREEZE.Nigel Cunningham
At the moment libata doesn't pass pm_message_t down ata_device_suspend. This causes drives to be powered down when we just want a freeze, causing unnecessary wear and tear. This patch gets pm_message_t passed down so that it can be used to determine whether to power down the drive.

2006-03-24[PATCH] libata: make ata_set_mode() responsible for failure handlingTejun Heo
Make ata_set_mode() responsible for determining whether to take port or device offline on failure. ata_dev_set_xfermode() and ata_dev_set_mode() indicate error to the caller instead of disabling port directly on failure. Also, for consistency, ata_dev_present() check is done in ata_set_mode() instead of ata_dev_set_mode(). Signed-off-by: Tejun Heo <htejun@gmail.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>

2006-03-24[PATCH] libata: implement ata_dev_disable()Tejun Heo
This patch implements ata_dev_disable() which prints a warning message and takes @dev offline. Currently, this is done by explicitly incrementing dev->class with case-by-case warning messages. Giving user clear indication when libata gives up will be more important as libata will be doing more retries. Signed-off-by: Tejun Heo <htejun@gmail.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>
2006-03-24[PATCH] libata: check if port is disabled after internal commandTejun Heo
libata core is being changed to disallow port/device disable on lower layers. However, some LLDDs (sata_mv) directly disable port on command failure. This patch makes ata_exec_internal() check whether a port got disabled after an internal command. If it is, AC_ERR_SYSTEM is added to err_mask and the port gets re-enabled. As internal command failure results in device disable for drivers which don't implement newer reset/EH callbacks, this change results in no behavior change for single device per port controllers. For slave-possible LLDDs which disable port on command failure, (1) such drivers don't exist currently, (2) issuing command to the other device of once-disabled port shouldn't result in catastrophe even if such driver exists. So, this should be enough as a temporary measure. Signed-off-by: Tejun Heo <htejun@gmail.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>
2006-03-24[PATCH] libata: make per-dev transfer mode limits per-devTejun Heo

The current code follows the spec but uses an overlong delay. This would be great if the hardware did. Several vendors however forget the D7 pulldown.

2006-03-22[PATCH] sg: use compound pagesNick Piggin
sg increments the refcount of constituent pages in its higher order memory allocations when they are about to be mapped by userspace. This is done so the subsequent get_page/put_page when doing the mapping and unmapping does not free the page. Move over to the preferred way, that is, using compound pages instead. This fixes a whole class of possible obscure bugs where a get_user_pages on a constituent page may outlast the user mappings or even the driver.

2006-03-22[PATCH] slab: Remove SLAB_NO_REAP optionChristoph Lameter
SLAB_NO_REAP is documented as an option that will cause this slab not to be reaped under memory pressure. However, that is not what happens. The only thing that SLAB_NO_REAP controls at the moment is the reclaim of the unused slab elements that were allocated in batch in cache_reap(). Cache_reap() is run every few seconds independently of memory pressure. Could we remove the whole thing? Its only used by three slabs anyways and I cannot find a reason for having this option. There is an additional problem with SLAB_NO_REAP. If set then the recovery of objects from alien caches is switched off. Objects not freed on the same node where they were initially allocated will only be reused if a certain amount of objects accumulates from one alien node (not very likely) or if the cache is explicitly shrunk. (Strangely __cache_shrink does not check for SLAB_NO_REAP) Getting rid of SLAB_NO_REAP fixes the problems with alien cache freeing.
