[PATCH] pstore: Headers should include all stuff they use

From: Anton Vorontsov
Date: Tue Jul 17 2012 - 14:39:05 EST


Headers should really include all the needed prototypes, types, defines
etc. to be self-contained. This is a long-standing issue, but apparently
the new tracing code unearthed it (SMP=n is also a prerequisite):

In file included from fs/pstore/internal.h:4:0,
from fs/pstore/ftrace.c:21:
include/linux/pstore.h:43:15: error: field âread_mutexâ has incomplete type

While at it, I also added the following:

linux/types.h -> size_t, phys_addr_t, uXX and friends
linux/spinlock.h -> spinlock_t
linux/errno.h -> Exxxx
linux/time.h -> struct timespec (struct passed by value)
struct module and rs_control forward declaration (passed via pointers).

I used 'git send-email' as normal, and it said:

Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit


OK, I checked what vger.kernel.org received, and it still says:

Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

And I see the email readable in the text editor.

OK, with linux_banner I got what the problem is, but where base64
came from?.. :-/

Anyways, resending w/ mutt.
