According to that history.git [1], then: drivers/video/pvr2fb.c had get_user_pages_fast() support added to pvr2fb_write() back in 2004, but only for CONFIG_SH_DMA, as part of commit 434502754f2 ("[PATCH] SH Merge") ...and that commit created the minor bug that patch 0001 here addresses. (+Cc Paul just for the sake of completeness.) [1] git://git.kernel.org/pub/scm/linux/kernel/git/tglx/history.git thanks,

And the commit I was looking for is in 2004. So that's why I needed a different stretch of history. thanks,

OK I see, neither a straight "git log" nor git branches will suffice, you have to use tags in order to get to the older versions. > >> while >> tglx/history.git *ends* at Linux 2.6.12-rc2 (which is in April, 2005). >> And the commit I was looking for is in 2004.
