Subject: [PATCH tip/x86/x32] fs: fix close_on_exec pointer in alloc_fdtable
Date: Wed, 22 Feb 2012 00:29:47 -0500 [thread overview]
Message-ID: <1329888587-3087-1-git-send-email-bobbypowers@gmail.com> (raw)
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.
