:Hello,
:
:as Matthew said in freebsd-current@ vfs_bio:getblk() still
:needs work (B_CACHE/B_DELWRI stuff).
:
:Running 3.0-stable (Jan 26) it still happens that some NFS
:writes seem to remain uncommited on the server.
:
:Is there a chance to get it into -stable before releasing
:in mid February?
:
: Thanks,
:
: Bjoern
Please try this diff ( against RELENG_3 kern/vfs_bio.c ) and
tell me if it works.
This is for STABLE only. Current already has this patch.
