2008-09-30	UBIFS: check data CRC when in error state	Artem Bityutskiy	1	-0/+1
	When UBIFS switches to R/O mode because of an error, it is reasonable to enable data CRC checking. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
2008-09-30	UBIFS: add no_chk_data_crc mount option	Adrian Hunter	1	-3/+8
	UBIFS read performance can be improved by skipping the CRC check when data nodes are read. This option can be used if the underlying media is considered to be highly reliable. Note that CRCs are always checked for metadata. Read speed on Arm platform with OneNAND goes from 19 MiB/s to 27 MiB/s with data CRC checking disabled.

2008-08-13	UBIFS: make ubifs_ro_mode() not inline	Adrian Hunter	1	-0/+14
	We use ubifs_ro_mode() quite a lot, and not in fast-path, so there is no reason to blow the code up by having it inlined. Also, we usually want R/O mode change to be seen to other CPUs as soon as possible, so when we make this a function call, we will automatically have a memory barrier.
