Not sure if it was the same before MFC, probably not, because what you see is impossible in case of source I'm looking at. At the begining of zfs_fuid_create() function there is a check: if (!zfsvfs->z_use_fuids || !IS_EPHEMERAL(id) || fuid_idx != 0) return (id); And IS_EPHEMERAL() is defined as follows: #define IS_EPHEMERAL(x) (0) So it will always return here. > #3 0xc08e95ce in zfs_fuid_create (zfsvfs=0xc65c4800, id=Unhandled dwarf > expression opcode 0x93 > ) > at > /usr/src/sys/modules/zfs/../../cddl/contrib/opensolaris/uts/common/fs/zfs/zfs_fuid.c:591 -- Pawel Jakub Dawidek http://www.wheel.pl p...@freebsd.org http://www.FreeBSD.org FreeBSD committer Am I Evil?
