2006-03-23[PATCH] kill cdrom ->dev_ioctl methodChristoph Hellwig3-31/+26
Since early 2.4.x all cdrom drivers implement the block_device methods themselves, so they can handle additional ioctls directly instead of going through the cdrom layer.

2006-03-22[PATCH] libata: Fix a drive detection problemAlan Cox1-0/+10
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. Fortunately 0xFF isnt a sane reset state so we can use it to skip detection as is done in drivers/ide.

2006-03-22[PATCH] sg: use compound pagesNick Piggin1-34/+3
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 Lameter1-1/+1
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.

Original patch (and description) by Douglas Gilbert, with minor fixes and API updates from me. Changelog: - make existing libata VPD device identification page (0x83) supply the ATA serial number in the libata "vendor specific" designator (from Chris Paulson-Ellis) - add a "t10 vendor id based" designator as defined in SAT rev 08 (section 10.3.4.2.3) that supplies ATA model and serial numbers - make the libata VPD page 0x83 more extensible (for adding more designators in the future). - rename EVPD to VPD in various places.
