Changes in dmu.c http://nxr.netbsd.org/rss/src/external/cddl/osnet/dist/uts/common/fs/zfs/dmu.c en Copyright 2005 Java Apply FreeBSD svn r373278 fix for ZFS corruption. Fix for NetBSD PR kern/58111 . It would be extremely unlikely to trip this bug on NetBSD, as we don't expose SEEK_DATA and SEEK_HOLE and you need to call ioctl(2) with FIOSEEKDATA and FIOSEEKHOLE directly which no currently known code does, and even then be unlucky enough to trip a race condition. With a reproducer based on that in https://www.illumos.org/issues/16087, I saw 11 groups of failures over 8 hours. With this patch, no failures in 10 hours. The repro for NetBSD will be attached to https://gnats.netbsd.org/58111 .

This code is not currently used, so no functional change, but it may be used when we hook zfs into the ubc. /src/external/cddl/osnet/dist/uts/common/fs/zfs/dmu.c - 1.4 Thu Mar 19 17:16:22 UTC 2015 riastradh Merge NetBSD local changes to new zfs version 22 sources. /src/external/cddl/osnet/dist/uts/common/fs/zfs/dmu.c - 1.3 Sat Feb 27 23:43:53 UTC 2010 haad Add some NetBSD fixes which I have forgot to commit during first round.
