r197287:
Purge namecache for the file system being rolled back, so it doesn't point at
invalid vnodes after the rollback resulting in EIO errors when trying to access
files which are in the namecache.
Reported by: des
r197289:
Purge file system namecache when receiving incremental stream and rolling back
to it.
r197351:
Purge namecache in the same place OpenSolaris does.
r197426:
Restore BSD behaviour - when creating new directory entry use parent directory
gid to set group ownership and not process gid.
This was overlooked during v6 -> v13 switch.
PR: kern/139076

r197458:
Close race in zfs_zget(). We have to increase usecount first and then
check for VI_DOOMED flag. Before this change vnode could be reclaimed
between checking for the flag and increasing usecount.
r197459:
Before calling vflush(FORCECLOSE) mark file system as unmounted so the
following vnops will fail. This is very important, because without this change
vnode could be reclaimed at any point, even if we increased usecount. The only
way to ensure that vnode won't be reclaimed was to lock it, which would be very
hard to do in ZFS without changing a lot of code. With this change simply
increasing usecount is enough to be sure vnode won't be reclaimed from under
us. To be precise it can still be reclaimed but we won't be able to see it,
because every try to enter ZFS through VFS will result in EIO.
The only function that cannot return EIO, because it is needed for vflush() is
zfs_root(). Introduce ZFS_ENTER_NOERROR() macro that only locks
z_teardown_lock and never returns EIO.
r197497:
Switch to fletcher4 as the default checksum algorithm. Fletcher2 was proven to
be a bit weak and OpenSolaris also switched to fletcher4.
r197498: head/cddl/contrib/opensolaris
Fletcher4 is not the default checksum algorithm.
r197512:
- Don't depend on value returned by gfs_*_inactive(), it doesn't work
well with forced unmounts when GFS vnodes are referenced.
- Make other preparations to GFS for forced unmounts.
PR: kern/139062

r197513:
Use traverse() function to find and return mount point's vnode instead of
covered vnode when snapshot is already mounted.
r197514:
On lookup error VFS expects *vpp to be set to NULL, be sure to do that.
r197515:
Handle cases where virtual (GFS) vnodes are referenced when doing forced
unmount. In that case we cannot depend on the proper order of invalidating
vnodes, so we have to free resources when we have a chance.
PR: kern/139062

r197525:
Ensure that tv_sec is between INT32_MIN and INT32_MAX, so ZFS won't object.
This completes the fix from r185586.
