Thanks for your patch! (Kosaki, thanks for your additional comments.) A few pointers for future patches: * Your subject line was good, but could have been even more descriptive. I changed the patch title to: mlock.2: Add EAGAIN error. * It's best to make the patch the very last piece of the message: put the Signed-off-by and other text above the patch. This makes the mail easier for me to read, and to process in git. I've applied your patch for 3.11.
