[PATCH] xfs: Use kmem_zalloc for bp->b_pages.

Change the allocation of bp->b_pages to use kmem_zalloc instead of kmem_alloc. Remove unnecessary memset for bp->b_pages. This reduces text size by 42 bytes. Before: textdata bss dec hex filename 23335 588 8 239315d7b ./fs/xfs/xfs_buf.o After: textdata

[PATCH v2 1/3] scripts/package/Makefile: put proper config in source tarball

It is widely known that one can build a kernel without a .config in the source tree by setting KCONFIG_CONFIG equal to the actual configuration file path. When making a *-pkg target, make(1) prepares a source tarball and tries to pack `.config' in there regardless of the value of KCONFIG_CONFIG,

[PATCH v2 3/3] package: {mkdebian,Makefile}: ignore .config in dpkg-source diffs

* We'd like to make dpkg-source ignore certain filepath patterns while producing the .diff.gz as part of a Debian source package. The relationship between dpkg-source's -i and --extend-diff-ignore options is quite complicated[1]. It's thus not very convenient to specify file path patterns
