I will experiment with a linux-next kernel and see if the problem recurs. I've attempted to see if there is a way to manually reproduce on the mainline kernel by performing workloads that triggered the OOM (loading google sheets tabs, compiling a kernel, playing a video on youtube), but to no avail - it seems the system needs to be sufficiently fragmented first before it'll trigger. Given that's the case, I'll just have to try using the linux-next kernel and if you don't hear from me you can assume it did not repro again :) I actually have a whole bunch of other OOM kill logs that I saved from previous occurrences of this issue, would it be useful for me to pastebin them, or would they not add anything of use beyond what's been shown in this thread? -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@xxxxxxxxx.
