https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D230160 --- Comment #7 from Bill Sorenson <instructionset@gmail.com> --- (In reply to David Chisnall from comment #6) I'm aware they have different use cases. My main point is that if we are go= ing to adopt a Linux-MADV_DONTNEED equivalent we use Illumos' MADV_PURGE rather than invent a new argument. I don't object to adding MADV_PURGE or MADV_ZERO for Linux compatibility bu= t to me it seems like it would usually be better to call munmap() directly than = to use some bizarre madvise() semantics to simulate it although admittedly I d= on't know the specifics. --=20 You are receiving this mail because: You are the assignee for the bug.=
