(PR/60004) (thus i didn't bother to implement RL_READER.) note: recent openzfs has a similar function. (zfs_rangelock_tryenter) this commit ought to be reverted when/if we switch to it. https://gnats.netbsd.org/cgi-bin/query-pr-single.pl?number=60004 Fri Feb 20 08:00:00 UTC 2026 yamt zfs: Expose hostid to zfs, as in gethostid/sethostid(3). If set to nonzero, the hostid is recorded in the metadata of a zpool, and checked by `zpool import' when the pool has not been explicitly exported. After reboot, zpool import will not need `-f' to reimport the pool. Setting the hostid must be done explicitly through sysctl (or the sethostid(3) library call) on all ports except acorn32, amiga, mvme68k, newsmips, sparc, sparc64, sun2, and sun3. So for most users this change will have no immediate effect. But you can obviate the need for `zpool import -f' by adding `kern.hostid=123456789' to /etc/sysctl.conf and importing the pool one last time with `-f'. Tue Dec 28 17:00:00 UTC 2021 riastradh Change dmu_diff() back to use a "file" instead of a "vnode". Command "zfs diff" calls it with a pipe, not a plain file. Fixes PR kern/54541: kernel panic using "zfs diff" Mon Oct 14 13:00:00 UTC 2019 hannken Try to retrieve the per-disk maximum transfer size and use it instead of MAXPHYS. Eagerly waiting for the merge of tls-maxphys. Addresses PR port-xen/54273: "zpool create pool xbd2" panics DOMU kernel Tue Jun 11 09:00:00 UTC 2019 hannken Enable the zvol minor management to create and remove device nodes. Wed May 22 08:00:00 UTC 2019 hannken Make ZFS exportable by NFS, implement zfsctl_vptofh(), zfs_netbsd_vptofh() and zfs_netbsd_fhtovp(). Undo changes to now completely unused zfs_fhtovp(). Mon Mar 18 09:00:00 UTC 2019 hannken Be consistent about _KERNEL vs _HARDKERNEL in zfs. As it happens, on x86 both _HARDKERNEL and _KERNEL get defined; see the conditional in sys/rump/Makefile.rump that _refrains_ from defining _RUMPKERNEL on x86. So the only version of this code that has been tested is the one with all of it included. But on, e.g., aarch64, we do not get _HARDKERNEL here, and the code fails to build because some things use the field struct spa::spa_deadman_cycid under _KERNEL when it is declared only under _HARDKERNEL. If there's a reason _not_ to use this in rump -- and it's not obvious to me why -- then all access to the field needs to agree to use _HARDKERNEL. Thu Nov 15 04:00:00 UTC 2018 riastradh merge a new version of the CDDL dtrace and ZFS code. this changes the upstream vendor from OpenSolaris to FreeBSD, and this version is based on FreeBSD svn r315983. in addition to the 10 years of improvements from upstream, this version also has these NetBSD-specific enhancements: - dtrace FBT probes can now be placed in kernel modules. - ZFS now supports mmap().
