mtd: nand: add a helper to detect the nand type

2013-10-27T23:27:06Z

This helper detects that whether the mtd's type is nand type. Now, it's clear that the MTD_NANDFLASH stands for SLC nand only. So use the mtd_type_is_nand() to replace the old check method to do the nand type (include the SLC and MLC) check. Signed-off-by: Huang Shijie Signed-off-by: Brian Norris

mtd: rename MTD_OOB_* to MTD_OPS_*

2011-09-11T12:28:59Z

These modes are not necessarily for OOB only. Particularly, MTD_OOB_RAW affected operations on in-band page data as well. To clarify these options and to emphasize that their effect is applied per-operation, we change the primary prefix to MTD_OPS_. Signed-off-by: Brian Norris Signed-off-by: Artem Bityutskiy

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: remove printk's for [kv][mz]alloc failures

2011-09-11T12:02:05Z

When a memory allocation fails, the kernel will print out a backtrace automatically. These print statements are unnecessary. Signed-off-by: Brian Norris Signed-off-by: Artem Bityutskiy

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] update internal API to support 64-bit device size

2008-12-10T13:37:21Z

MTD internal API presently uses 32-bit values to represent device size. This patch updates them to 64-bits but leaves the external API unchanged. Extending the external API is a separate issue for several reasons. First, no one needs it at the moment. Secondly, whether the implementation is done with IOCTLs, sysfs or both is still debated. Thirdly external API changes require the internal API to be accepted first. Note that although the MTD API will be able to support 64-bit device sizes, existing drivers do not and are not required to do so, although NAND base has been updated. In general, changing from 32-bit to 64-bit values cause little or no changes to the majority of the code with the following exceptions: - printk message formats - division and modulus of 64-bit values - NAND base support - 32-bit local variables used by mtdpart and mtdconcat - naughtily assuming one structure maps to another in MEMERASE ioctl Signed-off-by: Adrian Hunter Signed-off-by: Artem Bityutskiy Signed-off-by: David Woodhouse
