Really good question. I think it is doable but with a lot of time and passion only. After all there is no easy way to recreate the issue but you need to run the kernel for days to see if it's stable. (In reply to Guido from comment #115) > I already tried the patch (but not in combination with the script) and it > solved the problem of 100% cpu but still f2fs_gc remains stuck and doesnt > end the garbage collection, so the user cant shutdown in a safe manner. Must have overlooked that statement, sorry. For me both problems seem to be solved with the script and patch combination through, so might we worth a try (ofc. after you finished your current test). -- You may reply to this email to add a comment.
