| |
3.3-stable review patch. If anyone has any objections, please let me know.
------------------
From: Artem Bityutskiy <artem.bityutskiy@linux.intel.com>
commit cca84b569ebe3372b28949e00b0a3a17f87e2970 upstream.
The writebufsize concept was introduce by commit "0e4ca7e mtd: add writebufsize field to mtd_info struct" and it represents the maximum amount of data the device writes to the media at a time. This is an important parameter for UBIFS which is used during recovery and which basically defines how big a corruption caused by a power cut can be.
Set it to be equivalent to mtd->writesize because this is the maximum amount of data the driver writes at a time.
