Include <linux/mtd/compat.h> header for min_t definition instead of
providing our own one. Removes warnings in case of OneNAND support
enabled.

Although I thinks it's a bit silly to include <linux/mtd/compat.h>
just for min_t...

jffs2: cache data_crc results 2008-12-09T22:40:01+00:00 Ilya Yanok yanok@emcraft.com 2008-11-13T16:49:36+00:00 142a80ffc3b537a9c45acd2444a42a77f147c602 As we moved data_crc() invocation from jffs2_1pass_build_lists() to jffs2_1pass_read_inode() data_crc is going to be calculated on each inode access. This patch adds caching of data_crc() results. There is no significant improvement in speed (because of flash access caching added in previous patch I think, crc in RAM is really fast) but this patch impacts memory usage -- every b_node structure uses 12 bytes instead of 8.

jffs2: add buffer to cache flash accesses 2008-12-09T22:39:58+00:00 Ilya Yanok yanok@emcraft.com 2008-11-13T16:49:34+00:00 70741004dc28946cd82c7af6789c4ddb3fc94526 With this patch JFFS2 code allocates memory buffer of max_totlen size (size of the largest node, calculated during scan time) and uses it to store entire node. Speeds up loading. If malloc fails we use old ways to do things. Signed-off-by: Alexey Neyman <avn@emcraft.com> Signed-off-by: Ilya Yanok <yanok@emcraft.com>
