Subject: [PATCH v4 1/7] arch/sparc: Remove the check #ifndef __LINUX_SPINLOCK_TYPES_H
Date: Wed, 24 May 2017 17:55:09 -0600	[thread overview]
Message-ID: <1495670115-63960-2-git-send-email-babu.moger@oracle.com> (raw)
In-Reply-To: <1495670115-63960-1-git-send-email-babu.moger@oracle.com>

Saw these compile errors on SPARC when queued rwlock feature is enabled.

   CC      kernel/locking/qrwlock.o
In file included from ./include/asm-generic/qrwlock_types.h:5,
                  from ./arch/sparc/include/asm/qrwlock.h:4,
                  from kernel/locking/qrwlock.c:24:
./arch/sparc/include/asm/spinlock_types.h:5:3: error:
         #error "please don't include this file directly"

SPARC has this guard which causes compile error when spinlock_types.h
is included directly.
@ifndef __LINUX_SPINLOCK_TYPES_H
@ error "please don't include this file directly"
@endif

Remove this un-necessary "ifndef __LINUX_SPINLOCK_TYPES_H" stanza from SPARC.
