2007-04-22[MTD] Finish conversion mtd_blkdevs to use the kthread APIChristoph Hellwig1-23/+9
Remove waitqueue, 'exiting' flag and completion; use kthread APIs instead. Signed-off-by: Christoph Hellwig <hch@lst.de> Signed-off-by: David Woodhouse <dwmw2@infradead.org>
2007-04-19[MTD] mtd_blkdevs: Convert to use the kthread APIEric W. Biederman1-14/+5
thread_run is used intead of kernel_thread, daemonize, and mucking around blocking signals directly. Signed-off-by: Eric W. Biederman <ebiederm@xmission.com> Signed-off-by: David Woodhouse <dwmw2@infradead.org>

2006-11-28[MTD] Allow variable block sizes in mtd_blkdevsRichard Purdie1-6/+9
Currently, mtd_blkdevs enforces a block size of 512, even if the drivers can seemingly request a different size. This patch fixes mtd_blkdevs so block sizes other than 512 work correctly. Signed-off-by: Richard Purdie <rpurdie@openedhand.com> Signed-off-by: David Woodhouse <dwmw2@infradead.org>
2006-10-01[MTD] fix printk warningJeff Garzik1-1/+1
gcc spits out this warning: drivers/mtd/mtd_blkdevs.c: In function ‘do_blktrans_request’: drivers/mtd/mtd_blkdevs.c:72: warning: format ‘%ld’ expects type ‘long int’, but argument 2 has type ‘unsigned int’ This could be fixed any number of ways, including use of BUG(). rq_data_dir() only returns 0 or 1, so this entire case is superfluous. I did the most simple fix. Signed-off-by: Jeff Garzik <jeff@garzik.org> Signed-off-by: David Woodhouse <dwmw2@infradead.org>
2006-09-30[PATCH] Split struct request ->flags into two partsJens Axboe1-1/+1
Right now ->flags is a bit of a mess: some are request types, and others are just modifiers. Clean this up by splitting it into ->cmd_type and ->cmd_flags. This allows introduction of generic Linux block message types, useful for sending generic Linux commands to block devices. Signed-off-by: Jens Axboe <axboe@suse.de>
2006-03-31[PATCH] sem2mutex: drivers/mtd/Ingo Molnar1-16/+16
Semaphore to mutex conversion. The conversion was generated via scripts, and the result was validated automatically via a script as well.

2006-03-26BUG_ON() Conversion in drivers/mtd/Eric Sesterhenn1-2/+1
this changes if() BUG(); constructs to BUG_ON() which is cleaner, contains unlikely() and can better optimized away. Signed-off-by: Eric Sesterhenn <snakebyte@gmx.de> Signed-off-by: Adrian Bunk <bunk@stusta.de>
2006-01-08[PATCH] Add block_device_operations.getgeo block device methodChristoph Hellwig1-16/+9
HDIO_GETGEO is implemented in most block drivers, and all of them have to duplicate the code to copy the structure to userspace, as well as getting the start sector. This patch moves that to common code [1] and adds a ->getgeo method to fill out the raw kernel hd_geometry structure. For many drivers this means ->ioctl can go away now. [1] the s390 block drivers are odd in this respect. xpram sets ->start to 4 always which seems more than odd, and the dasd driver shifts the start offset around, probably because of it's non-standard sector size.

2005-08-04[MTD] mtd_blkdevs.c: Fix names when many devices/partitions are createdTodd Poynor1-3/+13
mtdblock (and other mtd modules that use the mtd_blkdevs interface between the mtd translation layers and the linux block layer) handles incorrectly more than 10 devices or 26 partitions in the names passed to the generic disk layer. This causes the device file names and other info kept by the generic disk/block layers to have names such as "mtdblock<". Use integer formatting for device numbers; use "aa-az" for partitions 27-52, "ba-bz" for 53-78... Signed-off-by: Todd Poynor <tpoynor@mvista.com> Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
2005-08-04[MTD] mtd_blkdevs.c: Remove DEVFS leftoversTodd Poynor1-7/+1
Remove mtd_blkdevs refs to the no longer functional DEVFS filesystem. Verified mtdblock continues to work fine via udev with these calls removed. Signed-off-by: Todd Poynor <tpoynor@mvista.com> Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
2005-04-16Linux-2.6.12-rc2v2.6.12-rc2Linus Torvalds1-0/+478
Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
