mtd: mtdblock: remove the needless mtdblks_lock

2015-01-07T20:51:56Z

The global lock mtdblks_lock was used to protect the original mtdblks array to avoid race conditions. As the mtdblks array was already gone, but the mtdblks_lock is left, and it causes latency when open/release dev. So we need to remove it here. Signed-off-by: Gu Zheng Signed-off-by: Brian Norris

mtd: Move major number definitions to major.h

2013-11-07T07:32:59Z

This patch moves the char and block major number definitions to major.h to be with the rest of the major numbers. While doing this, include major.h in the files that need it. Signed-off-by: Ezequiel Garcia Signed-off-by: Brian Norris

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: 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).

mtd: do not use mtd->sync directly

2012-01-09T18:26:21Z

This patch teaches 'mtd_sync()' to do nothing when the MTD driver does not have the '->sync()' method, which allows us to remove all direct 'mtd->sync' accesses. Signed-off-by: Artem Bityutskiy Signed-off-by: David Woodhouse

mtd: introduce mtd_erase interface

2012-01-09T18:25:11Z

This patch is part of a patch-set which changes the MTD interface from 'mtd->func()' form to 'mtd_func()' form. We need this because we want to add common code to to all drivers in the mtd core level, which is impossible with the current interface when MTD clients call driver functions like 'read()' or 'write()' directly. At this point we just introduce a new inline wrapper function, but later some of them are expected to gain more code. E.g., the input parameters check should be moved to the wrappers rather than be duplicated at many drivers. This particular patch introduced the 'mtd_erase()' interface. The following patches add all the other interfaces one by one. Signed-off-by: Artem Bityutskiy Signed-off-by: David Woodhouse
