I see a pattern here but still not 100% sure. 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. Anyway if I will have the 100% cpu problem in the following days, I'll try it. -- You may reply to this email to add a comment.
