The patch titled block: reorder struct bio to remove padding on 64bit has been removed from the -mm tree. Its filename was block-reorder-struct-bio-to-remove-padding-on-64bit.patch This patch was dropped because it was merged into mainline or a subsystem tree The current -mm tree may be found at http://userweb.kernel.org/~akpm/mmotm/ ------------------------------------------------------ Subject: block: reorder struct bio to remove padding on 64bit From: Richard Kennedy <richard@xxxxxxxxxxxxxxx> Remove 8 bytes of padding from struct bio which also removes 16 bytes from struct bio_pair to make it 248 bytes. bio_pair then fits into one fewer cache lines & into a smaller slab.
