Doesn't apply cleanly to net: Applying: tcp: Prevent low rmem stalls with SO_RCVLOWAT. error: sha1 information is lacking or useless (net/ipv4/tcp.c). error: could not build fake ancestor hint: Use 'git am --show-current-patch=diff' to see the failed patch Patch failed at 0001 tcp: Prevent low rmem stalls with SO_RCVLOWAT. When you have resolved this problem, run "git am --continue". If you prefer to skip this patch, run "git am --skip" instead. To restore the original branch and stop patching, run "git am --abort".
