JFFS2 FS Isolated task block times!



Ok, here are the latency jitter times for a (POSIX) real time Linux task
running BUT NOT INTERACTING directly with the JFFS2 fs.
It's mind bloggling. Why is the kernel being blocked for 10's of seconds
due to the JFFS2 activity? What is the GC doing that is not releasing
the kernel?

See the graph at: (The RED graph is the non-JFFS2-interaction task, the
green one is a task that reads/writes to the JFFS2 fs)
