https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D263971 --- Comment #4 from Kirk McKusick <mckusick@FreeBSD.org> --- (In reply to Robert Morris from comment #3) I have tried to further restrict the values that I accept for fs_cssize, fs_ncg, and fs_contigsumsize. And also put a limit on the size of the filesystem that can be mounted based on kernel memory limits. --=20 You are receiving this mail because: You are the assignee for the bug.
