mtd: inftlcore: Add error check for inftl_read_oob()

2025-04-07T07:02:31+00:00

In INFTL_findwriteunit(), the return value of inftl_read_oob() need to be checked. A proper implementation can be found in INFTL_deleteblock(). The status will be set as SECTOR_IGNORE to break from the while-loop correctly if the inftl_read_oob() fails.

mtd: always initialize 'stats' in struct mtd_oob_ops

2022-09-21T08:38:07+00:00

As the 'stats' field in struct mtd_oob_ops is used in conditional expressions, ensure it is always zero-initialized in all such structures to prevent random stack garbage from being interpreted as a pointer. Strictly speaking, this problem currently only needs to be fixed for struct mtd_oob_ops structures subsequently passed to mtd_read_oob(). However, this commit goes a step further and makes all instances of struct mtd_oob_ops in the tree zero-initialized, in hope of preventing future problems, e.g. if struct mtd_req_stats gets extended with write statistics at some point.

mtd: nand: Rename nand.h into rawnand.h

2017-08-13T08:11:49+00:00

We are planning to share more code between different NAND based devices (SPI NAND, OneNAND and raw NANDs), but before doing that we need to move the existing include/linux/mtd/nand.h file into include/linux/mtd/rawnand.h so we can later create a nand.h header containing all common structure and function prototypes.

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

2013-10-27T23:27:06+00:00

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: add leading underscore to all mtd functions

2012-03-26T23:20:01+00:00

This patch renames all MTD functions by adding a "_" prefix: mtd->erase -> mtd->_erase mtd->read_oob -> mtd->_read_oob ... The reason is that we are re-working the MTD API and from now on it is an error to use MTD function pointers directly - we have a corresponding API call for every pointer. By adding a leading "_" we achieve the following: 1. Make sure we convert every direct pointer users 2. A leading "_" suggests that this interface is internal and it becomes less likely that people will use them directly 3. Make sure all the out-of-tree modules stop compiling and the owners spot the big API change and amend them. Signed-off-by: Artem Bityutskiy Signed-off-by: David Woodhouse
