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: Convert logging messages

2013-08-05T19:47:17Z

Use a more current logging style. Convert homegrown ERROR/INFO macros to pr_. Convert homegrown parse_err macros to pr_err and expand hidden flow control. Signed-off-by: Joe Perches Signed-off-by: Artem Bityutskiy Signed-off-by: David Woodhouse

mtd: block2mtd: throttle writes by calling balance_dirty_pages_ratelimited.

2012-12-13T11:39:44Z

If you create a block2mtd device that is larger than main memory, and write to all of it, then lots of pages will be dirtied but they will never be flushed out as nothing calls any variant of balance_dirty_pages. It would be nice to call set_page_dirty_balance(), but that isn't exported, so just call balance_dirty_pages_ratelimited() directly. Signed-off-by: NeilBrown Signed-off-by: Artem Bityutskiy

mtd: remove use of __devexit

2012-11-22T10:07:03Z

CONFIG_HOTPLUG is going away as an option so __devexit is no longer needed. Signed-off-by: Bill Pemberton Signed-off-by: Artem Bityutskiy

mtd: block2mtd: fix recursive call of mtd_writev

2012-06-01T19:23:19Z

The 'mtd_writev' interface calls the function assigned to the '_write' field of a given mtd device if that is not NULL. The block2mtd driver sets the '_writev' field to the 'mtd_writev' function itself and thus causes a endless loop. This is caused by 1dbebd32562b3c2caeca35960e5cb00bfcc12900 (mtd: harmonize mtd_writev usage). Remove the assignment from the block2mtd driver to fix the issue.

mtd: block2mtd: page_read() never returns NULL

2012-05-14T03:56:52Z

page_read() never returns NULL, so we can remove the NULL check here. Signed-off-by: Ryosuke Saito Signed-off-by: Artem Bityutskiy Signed-off-by: David Woodhouse

mtd: move zero length verification to MTD API functions

2012-03-26T23:32:19Z

In many places in drivers we verify for the zero length, but this is very inconsistent across drivers. This is obviously the right thing to do, though. This patch moves the check to the MTD API functions instead and removes a lot of duplication. Signed-off-by: Artem Bityutskiy Reviewed-by: Shmulik Ladkani Signed-off-by: David Woodhouse

mtd: remove retlen zeroing duplication

2012-03-26T23:29:34Z

The MTD API function now zero the 'retlen' parameter before calling the driver's method — do not do this again in drivers. This removes duplicated '*retlen = 0' assignent from the following methods: 'mtd_point()' 'mtd_read()' 'mtd_write()' 'mtd_writev()' 'mtd_panic_write()' Signed-off-by: Artem Bityutskiy Signed-off-by: David Woodhouse
