[Xen-devel] [PATCH 0/2] whitespace cleanup in Linux sparse tree
The following two patches are another pass through low hanging fruit for reducing the size of the Linux sparse patch. Here I simply remove all extraneous whitespace changes (broken up into i386 and x86_64 patches). The actual patch file drops about 7k in size, below are the diffstat differences. Current: $ ./mkpatch | diffstat | tail -1 76 files changed, 6599 insertions(+), 5630 deletions(-) With i386 whitespace changes removed (patch 1/2) $ ./mkpatch | diffstat | tail -1 76 files changed, 6572 insertions(+), 5605 deletions(-) With both i386 and x86_64 whitespace changes removed (patch 2/2): $ ./mkpatch | diffstat | tail -1 76 files changed, 6476 insertions(+), 5511 deletions(-) _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel
