[David Woodhouse]

Update of /home/cvs/mtd/include/linux
In directory phoenix.infradead.org:/tmp/cvs-serv25358/include/linux

Modified Files:
	jffs2_fs_sb.h 
Log Message:
Wheee. Late checking of CRC makes the mount time somewhat better. We can improve this
but it's OK as a proof-of-concept.

Some benchmark times on recent code changes with a 14M mtdram device (hence not a great
deal of improvement from point code):

point, list code  0.291s
read,  list code  0.299s
point, tree code  0.282s
read,  tree code  0.292s
point, tree, no data crc 0.123s
point, tree, no inode crc 0.112s
point, tree, scan just-in-time 0.080s
point, tree, scan just-in-time, D1(PARANOIA), 0.050s
