Thanks
I see
<https://github.com/openzfs/zfs/commit/5cc1876f14f90430b24f1ad2f231de936691940f>, with <https://github.com/freebsd/freebsd-src/commit/9dcf00aa404bb62052433c45aaa5475e2760f5ed> in stable/14.
As vfs.zfs.bclone_enabled is still 0 (at least, with 15.0-CURRENT
n265350-72d97e1dd9cc): should we assume that additional fixes, not
necessarily in time for 14.0-RELEASE, will be required before
vfs.zfs.bclone_enabled can default to 1?
I am not aware of any block cloning issues now. All this thread about
bclone_enabled actually started after I asked why it is still disabled.
Thanks to Mark Millard for spotting this issue I could fix, but now we
are back at the point of re-enabling it again. Since the tunable does
not even exist anywhere outside of FreeBSD base tree, I'd propose to
give this code another try here too. I see no point to have it disabled
at least in main unless somebody needs time to run some specific tests
first.
