In the following commit one can see that most of its code was moved or copied from mm/filemap.c: https://git.kernel.org/pub/scm/linux/kernel/git/tglx/history.git/commit/?id=882ad449046cec136c484dd2b3659fb4c683e0a3 filemap.c has a copyright line by Linus, but git blame shows that the relevant code was added in 2002 with a commit by Rik van Riel: https://git.kernel.org/pub/scm/linux/kernel/git/tglx/history.git/commit/?id=e5191c50d12621e04f8bc247dcb6a0f4ad76ae26 The relevant thread in LKML is here: https://lkml.org/lkml/2002/2/18/1970 Ulrich
