Yes, it will be removed some time before 10.0. Right now I opted to not change mpsafe filesystem modules. An option was to keep the code which refused to mount filesystem without MNTK_MPSAFE set, but I decided to cut the whole tail once. But I did not wanted to touch working mpsafe filesystems, thus MNTK_MPSAFE survived yet. --i9pGKxSHTiGLjQSm Content-Type: application/pgp-signature -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.19 (FreeBSD) iEYEARECAAYFAlCaexYACgkQC3+MBN1Mb4iXbQCgl/foIv1y4q6ilOt8TY632aOV lCEAnjU/Sah4fvQfGWxdgwFUp7HXtOpH =eSlz -----END PGP SIGNATURE----- --i9pGKxSHTiGLjQSm--
