* mtd: Few follow up cleanups for Smartmedia/xD supportMaxim Levitsky2010-02-261-1/+0
| | | | | | | | | | * Test results of few functions that were declared with __must_check * Fix bogus gcc warning about uinitialized variable 'ret' * Remove unused variable from mtdblock_remove_dev * Don't use deprecated DMA_32BIT_MASK Signed-off-by: Maxim Levitsky <maximlevitsky@gmail.com> Signed-off-by: David Woodhouse <David.Woodhouse@intel.com>
* mtd: mtdblock: test return value of add_mtd_blktrans_dev, because if can failMaxim Levitsky2010-02-261-1/+2

* mtd: blktrans: Hotplug fixesMaxim Levitsky2010-02-261-2/+0
| | | | | | | | | | | | | | | | | | | * Add locking where it was missing. * Don't do a get_mtd_device in blktrans_open because it would lead to a deadlock; instead do that in add_mtd_blktrans_dev. * Only free the mtd_blktrans_dev structure when the last user exits. * Flush request queue on device removal. * Track users, and call tr->release in del_mtd_blktrans_dev Due to that ->open and release aren't called more that once. Now it is safe to call del_mtd_blktrans_dev while the device is still in use. Signed-off-by: Maxim Levitsky <maximlevitsky@gmail.com> Signed-off-by: David Woodhouse <David.Woodhouse@intel.com>
* mtd: mtdblock: Dynamically allocate cache info structuresBen Hutchings2010-02-251-43/+31
| | | | | | | | | | | | | | | Since we allocate struct mtd_blktrans_dev for each block device, we can add our own structure members to the end. Therefore embed struct mtd_blktrans_dev in struct mtdblk_dev and remove the static array of struct mtdblk_dev. Also remove the redundant pointer to struct mtd_info. This is preparation for removing the static limit on the number of MTD devices.

* MTD/JFFS2: remove CVS keywordsAdrian Bunk2008-06-041-2/+0
| | | | | | | | | | | | Once upon a time, the MTD repository was using CVS. This patch therefore removes all usages of the no longer updated CVS keywords from the MTD code. This also includes code that printed them to the user. Signed-off-by: Adrian Bunk <bunk@kernel.org> Signed-off-by: David Woodhouse <dwmw2@infradead.org>

* [MTD] Allow variable block sizes in mtd_blkdevsRichard Purdie2006-11-281-1/+2
| | | | | | | | | 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>

* [MTD] replace MTD_RAM with MTD_GENERIC_TYPEJoern Engel2006-05-301-1/+1
| | | | | | | | Ram devices get the extra capability of MTD_NO_ERASE - not requiring an explicit erase before writing to it. Currently only mtdblock uses this capability. Rest of the patch is a simple text replacement. Signed-off-by: Joern Engel <joern@wh.fh-wedel.de>
* [MTD] Remove silly MTD_WRITE/READ macrosThomas Gleixner2006-05-291-6/+7
| | | | | | | Most of those macros are unused and the used ones just obfuscate the code. Remove them and fixup all users. Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
* Simplify test for RAM devicesJörn Engel2006-04-171-2/+1
| | | | | | | | | | | mtdblock is the only user of aggregate capabilities in mtd. This is clearly bogus and should be changed. In particular, it tries to determine whether the device in question is a piece of RAM. For every single driver that fits the current criteria, an easier test would be to check for the type being MTD_RAM.

* [PATCH] fix missing includesTim Schmielau2005-10-301-0/+1
| | | | | | | | | | | | | | | | | | | | | I recently picked up my older work to remove unnecessary #includes of sched.h, starting from a patch by Dave Jones to not include sched.h from module.h. This reduces the number of indirect includes of sched.h by ~300. Another ~400 pointless direct includes can be removed after this disentangling (patch to follow later). However, quite a few indirect includes need to be fixed up for this. In order to feed the patches through -mm with as little disturbance as possible, I've split out the fixes I accumulated up to now (complete for i386 and x86_64, more archs to follow later) and post them before the real patch. This way this large part of the patch is kept simple with only adding #includes, and all hunks are independent of each other. So if any hunk rejects or gets in the way of other patches, just drop it. My scripts will pick it up again in the next round.

* Linux-2.6.12-rc2v2.6.12-rc2Linus Torvalds2005-04-161-0/+394
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!
