mtd_blktrans_ops->release() should return void

2013-05-06T01:31:22Z

Both existing instances always return 0 and even if they didn't, the value would be lost on the way out. Just don't bother... Signed-off-by: Al Viro

mtd: mtd_blkdevs: Replace request handler kthread with a workqueue

2012-11-21T15:02:23Z

By replacing a kthread with a workqueue, the code is now a bit clearer. There's also a slight reduction of code size (numbers apply for x86): Before: text data bss dec hex filename 3248 36 0 3284 cd4 drivers/mtd/mtd_blkdevs.o After: text data bss dec hex filename 3150 36 0 3186 c72 drivers/mtd/mtd_blkdevs.o Due to lack of real hardware, tests have been performed on an emulated environment with mtdswap and mtdblock over nandsim devices. Some real testing should be done, before merging this patch. Signed-off-by: Ezequiel Garcia Signed-off-by: Artem Bityutskiy

mtd: mtdblock: call mtd_sync() only if opened for write

2012-03-26T23:11:11Z

Because it is useless to call it if the device is opened in R/O mode, and also harmful: on CFI NOR flash it may block for long time waiting for erase operations to complete is another partition with a R/W file-system on this chip. Artem Bityutskiy: write commit message, amend the patch to match the latest tree (we use mtd_sync(), not mtd->sync() nowadays).

Merge branch 'master' of git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux-2.6 into for-linus-1

* 'master' of git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux-2.6: (9356 commits) [media] rc: update for bitop name changes fs: simplify iget & friends fs: pull inode->i_lock up out of writeback_single_inode fs: rename inode_lock to inode_hash_lock fs: move i_wb_list out from under inode_lock fs: move i_sb_list out from under inode_lock fs: remove inode_lock from iput_final and prune_icache fs: Lock the inode LRU list separately fs: factor inode disposal fs: protect inode->i_state with inode->i_lock lib, arch: add filter argument to show_mem and fix private implementations SLUB: Write to per cpu data when allocating it slub: Fix debugobjects with lockless fastpath autofs4: Do not potentially dereference NULL pointer returned by fget() in autofs_dev_ioctl_setpipefd() autofs4 - remove autofs4_lock autofs4 - fix d_manage() return on rcu-walk autofs4 - fix autofs4_expire_indirect() traversal autofs4 - fix dentry leak in autofs4_expire_direct() autofs4 - reinstate last used update on access vfs - check non-mountpoint dentry might block in __follow_mount_rcu() ... NOTE! This merge commit was created to fix compilation error. The block tree was merged upstream and removed the 'elv_queue_empty()' function which the new 'mtdswap' driver is using. So a simple merge of the mtd tree with upstream does not compile. And the mtd tree has already be published, so re-basing it is not an option. To fix this unfortunate situation, I had to merge upstream into the mtd-2.6.git tree without committing, put the fixup patch on top of this, and then commit this. The result is that we do not have commits which do not compile. In other words, this merge commit "merges" 3 things: the MTD tree, the upstream tree, and the fixup patch.

mtd_blkdevs: Add background processing support

2011-03-11T14:22:46Z

Add a new background method into mtd_blktrans_ops, add background support into mtd_blktrans_thread(), and add mtd_blktrans_cease_background(). If the mtd blktrans dev has the background support, the thread will call background function when the request queue becomes empty. The background operation may run as long as needs to until mtd_blktrans_cease_background() tells to stop. Signed-off-by: Jarkko Lavinen Tested-by: Artem Bityutskiy Signed-off-by: David Woodhouse

mtd: blktrans: allow FTL drivers to export sysfs attributes

2010-02-26T17:37:40Z

This patch adds an ability to export sysfs attributes below the block disk device. This can be used to pass the udev an information about the FTL and could include the vendor, serial, version, etc... Signed-off-by: Maxim Levitsky Signed-off-by: David Woodhouse

mtd: blktrans: Hotplug fixes

2010-02-26T17:05:26Z

* 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 Signed-off-by: David Woodhouse

mtd: blktrans: remove mtd_blkcore_priv, switch to per device queue and thread

2010-02-26T17:04:03Z

This is the biggest change. To make hotplug possible, and this layer clean, the mtd_blktrans_dev now contains everything for a single mtd block translation device. Also removed some very old leftovers. Signed-off-by: Maxim Levitsky Signed-off-by: David Woodhouse
