mmc: Add missing sg_init_table() call

2007-11-27T08:19:40Z

mmc_init_queue only initializes the scatterlists with sg_init_table() when using a bounce buffer. This leads to a BUG() when CONFIG_DEBUG_SG is set. Signed-off-by: Haavard Skinnemoen Signed-off-by: Jens Axboe

mmc: Fix sg helper copy-and-paste error

2007-11-08T12:50:58Z

Commit 45711f1a ("[SG] Update drivers to use sg helpers") had the following bogus change in drivers/mmc/card/queue.c: > - src_buf = page_address(src->page) + src->offset; > + src_buf = sg_virt(dst); (Notice that "src" is converted to "dst"). Turn this "dst" back into the intended "src". Signed-off-by: Roland Dreier Tested-by: Romano Giannetti Signed-off-by: Jens Axboe

mmc: need to zero sglist on init

2007-10-16T09:24:45Z

Otherwise we could have junk in the sg fields, fooling the sg chaining into thinking ->page is valid. Acked-by: Pierre Ossman Signed-off-by: Jens Axboe

mmc: reorganize bounce buffer init

2007-08-09T12:37:17Z

Reorganize the code that initializes mmc_block's bounce buffer in order to avoid warnings when MMC_BLOCK_BOUNCE isn't used. Signed-off-by: Pierre Ossman

[BLOCK] Get rid of request_queue_t typedef

2007-07-24T07:28:11Z

Some of the code has been gradually transitioned to using the proper struct request_queue, but there's lots left. So do a full sweet of the kernel and get rid of this typedef and replace its uses with the proper type. Signed-off-by: Jens Axboe

Freezer: make kernel threads nonfreezable by default

2007-07-17T17:23:02Z

Currently, the freezer treats all tasks as freezable, except for the kernel threads that explicitly set the PF_NOFREEZE flag for themselves. This approach is problematic, since it requires every kernel thread to either set PF_NOFREEZE explicitly, or call try_to_freeze(), even if it doesn't care for the freezing of tasks at all. It seems better to only require the kernel threads that want to or need to be frozen to use some freezer-related code and to remove any freezer-related code from the other (nonfreezable) kernel threads, which is done in this patch. The patch causes all kernel threads to be nonfreezable by default (ie. to have PF_NOFREEZE set by default) and introduces the set_freezable() function that should be called by the freezable kernel threads in order to unset PF_NOFREEZE. It also makes all of the currently freezable kernel threads call set_freezable(), so it shouldn't cause any (intentional) change of behaviour to appear. Additionally, it updates documentation to describe the freezing of tasks more accurately. [akpm@linux-foundation.org: build fixes] Signed-off-by: Rafael J.

mmc: bounce requests for simple hosts

2007-07-09T19:22:53Z

Some hosts cannot do scatter/gather in hardware. Since not doing sg is such a big performance hit, we (optionally) bounce the requests to a simple linear buffer that we hand over to the driver. Signed-off-by: Pierre Ossman
