https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=230160 --- 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 going 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 but 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 don't know the specifics. -- You are receiving this mail because: You are the assignee for the bug.help
