New Revision: 297232
URL: https://svnweb.freebsd.org/changeset/base/297232
Log:
Unify ignoring EEXIST from zvol_create_minor().
This fixes creation of zvol devices for snapshots during zfs receive,
that previously failed with "ZFS WARNING: Unable to create ZVOL" message.
This solution is not perfect, but IMHO better then it was before.
