Subject: [PATCH] Use __kernel_long_t in struct mq_attr
Date: Wed, 25 Dec 2013 08:58:34 -0800	[thread overview]
Message-ID: <20131225165834.GA1526@gmail.com> (raw)

Both x32 and x86-64 use the same struct mq_attr for system calls.  But
x32 long is 32-bit. This patch replaces long with __kernel_long_t in
struct mq_attr.
