[MTD] Fix length comparison in MEMREADOOB

2007-04-17T17:40:00Z

The ops.len member is not initialized, because it is unused for this operation. The length check needs to use ops.ooblen instead Signed-off-by: Thomas Gleixner Signed-off-by: David Woodhouse

[PATCH] mark struct file_operations const 5

2007-02-12T17:48:45Z

Many struct file_operations in the kernel can be "const". Marking them const moves these to the .rodata section, which avoids false sharing with potential dirty data. In addition it'll catch accidental writes at compile time to these shared resources. Signed-off-by: Arjan van de Ven Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

[MTD] remove unused ecctype,eccsize fields from struct mtd_info

2007-02-09T15:27:12Z

Remove unused and broken mtd->ecctype and mtd->eccsize fields from struct mtd_info. Do not remove them from userspace API data structures (don't want to breake userspace) but mark them as obsolete by a comment. Any userspace program which uses them should be half-broken anyway, so this is more about saving data structure size. Signed-off-by: Artem Bityutskiy Signed-off-by: David Woodhouse

[MTD] return error code from get_mtd_device()

2006-11-29T15:06:38Z

get_mtd_device() returns NULL in case of any failure. Teach it to return an error code instead. Fix all users as well. Signed-off-by: Artem Bityutskiy

[MTD] [NAND] remove len/ooblen confusion.

2006-11-28T22:39:03Z

As was discussed between Ricard Wanderlöf, David Woodhouse, Artem Bityutskiy and me, the current API for reading/writing OOB is confusing. The thing that introduces confusion is the need to specify ops.len together with ops.ooblen for reads/writes that concern only OOB not data area. So, ops.len is overloaded: when ops.datbuf != NULL it serves to specify the length of the data read, and when ops.datbuf == NULL, it serves to specify the full OOB read length. The patch inlined below is the slightly updated version of the previous patch serving the same purpose, but with the new Artem's comments taken into account. Artem, BTW, thanks a lot for your valuable input! Signed-off-by: Vitaly Wool Signed-off-by: David Woodhouse

[MTD] mtdchar: Fix MEMGETOOBSEL and ECCGETLAYOUT ioctls

2006-10-21T15:33:17Z

1. The ECCGETLAYOUT ioctl copy_to_user() call has a superfluous '&' causing the resulting information to be garbage rather than the intended mtd->ecclayout. 2. The MEMGETOOBSEL misses copying mtd->ecclayout->eccbytes so the resulting field of the returned structure contains garbage. Signed-off-by: Ricard Wanderlöf Signed-off-by: David Woodhouse
