It looks like you included all bits we found in the previous runs, so likely it will work good, but so far I have conflicts merging todays git and your tree in include/linux/splice.h, fs/ext2/file.c, fs/splice.c and mm/filemap_xip.c. This can be a problem with my tree though. It really looks like the last tree we tested, so if you think additional one will not hurt, feel free to ping, so I will completely rebase testing tree. > -- > Jens Axboe -- Evgeniy Polyakov
