The patch titled BINFMT: fill_elf_header cleanup - use straight memset first has been removed from the -mm tree. Its filename was binfmt-fill_elf_header-cleanup-use-straight-memset-first.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: BINFMT: fill_elf_header cleanup - use straight memset first From: Cyrill Gorcunov <gorcunov@xxxxxxxxx> This patch does simplify fill_elf_header function by setting to zero the whole elf header first.
