Linus,
I posted this morning on this problem again becaue your earlier
description of this was not clear relative to pre-8 -- at least not
directly enough for someone as apparently dense as I am to understand.
I was under the impression that pre8 corrected the flushing problem for
commit_write(). What's really weird about the code I posted this
morning is that this is an implementation I did that USES BUFFER HEADS
FROM THE BUFFER CACHE that are on the LRU list in your code and they are
still not getting flushed.
Any help here would be appreciated.
:-)
Jeff
