From 140dfd00ae544cdc0c9951b80ad6df61e62859e2 Mon Sep 17 00:00:00 2001 From: Alex Chiang Date: Tue, 1 Apr 2008 11:21:40 -0400 Subject: [PATCH] btrfs-progs: Stop stomping on 'name' input parameter In btrfs_name_hash, Local variable 'buf' is declared as __u32 buf[2]; but we then try to do this: buf[0] = 0x67452301; buf[1] = 0xefcdab89; buf[2] = 0x98badcfe; buf[3] = 0x10325476; Oops. Fix buf to be the proper size.
