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

mtd: replace DEBUG() with pr_debug()

2011-09-11T12:02:16Z

Start moving away from the MTD_DEBUG_LEVEL messages. The dynamic debugging feature is a generic kernel feature that provides more flexibility. (See Documentation/dynamic-debug-howto.txt) Also fix some punctuation, indentation, and capitalization that went along with the affected lines.

mtd: mtdblock: Use DEFINE_MUTEX() for mtdblks_lock

mtdblks_lock can be initialized automatically with DEFINE_MUTEX() rather than explicitly calling mutex_init(). Signed-off-by: Axel Lin Signed-off-by: Artem Bityutskiy
