Author: kevans Date: Wed Feb 27 17:00:14 2019 New Revision: 344624 URL: https://svnweb.freebsd.org/changeset/base/344624 Log: MFC r344218: mdmfs(8): use -o reserve with malloc-backed md(4) Mentioned in mdconfig(8), malloc-backed md(4) can be unstable unless required memory is allocated up front with -o reserve. Furthermore, panics have been observed with md used in fstab on 12.0-RELEASE. Choose the stable route and pass -o reserve.
