From 0ceacf36e9c41859a6072342d27cf6e60776c523 Mon Sep 17 00:00:00 2001 From: Brian Norris Date: Sun, 19 Sep 2010 23:57:12 -0700 Subject: mtd: edit comments on deprecation of ioctl ECCGETLAYOUT There were some improvements and additions necessary in the comments explaining of the expansion of nand_ecclayout, the introduction of nand_ecclayout_user, and the deprecation of the ioctl ECCGETLAYOUT. Also, I found a better placement for the macro MTD_MAX_ECCPOS_ENTRIES; next to the definition of MTD_MAX_OOBFREE_ENTRIES in mtd-abi.h. The macro is really only important for the ioctl code (found in drivers/mtd/mtdchar.c) but since there are small edits being made to the user-space header, I figured this is a better location.
