From f044db4cb4bf16893812d35b5fbeaaf3e30c9215 Mon Sep 17 00:00:00 2001 From: Bobby Powers Date: Wed, 22 Feb 2012 00:29:47 -0500 Subject: [PATCH] fs: Fix close_on_exec pointer in alloc_fdtable alloc_fdtable allocates space for the open_fds and close_on_exec bitfields together, as 2 * nr / BITS_PER_BYTE. close_on_exec needs to point to open_fds + nr / BITS_PER_BYTE, not open_fds + nr / BITS_PER_LONG, as introducted in 1fd36adc: Replace the fd_sets in struct fdtable with an array of unsigned longs.
