Hi,
It looks like there is a long delay before filesystem becomes available
after mount returns. Test setup: jffs2 on 256 MByte NAND chip, 2.6.10 linux
with recent mtd snapshot. Filesystem contains one 200 MByte file written
and fsynced in 1 kByte chunks. Checking ps it appears that gcd was the only
thing running (RWN).
Mount and touch were run immediately one after another. I think it may be
related to the long umount time problem that I reported before. At least
the symptoms are similar: something is still going on after mount completes.
Note negligible user and sys times during touch.
# time mount /mnt/flash/
real 1m33.538s
user 0m0.020s
sys 1m33.421s
# time touch /mnt/flash/junk
real 11m10.058s
user 0m0.010s
sys 0m0.010s
