I thought the OOM problems from 4.7 we're supposed to be fixed in 4.8, or did I get that wrong? No users or anything else on the system. ^ permalink raw reply [flat|nested] 3+ messages in thread

Keep in mind that those problems are generic, other filesystems also suffer: http://www.spinics.net/lists/linux-mm/msg114123.html I don't see any recent compaction-related patches in Linus' tree at https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/log/mm/ ..so it seems they have not been merged yet. So unless they get merged in the last minute it looks like 4.8 will be DOA. -h ^ permalink raw reply [flat|nested] 3+ messages in thread

That went into 4.8rc8 already, so not sure what happened in your case. > So unless they get merged in the last minute it looks like 4.8 will > be DOA. Running 4.8 final now, let's see what happens.. -h ^ permalink raw reply [flat|nested] 3+ messages in thread
