Subject: [for-next][PATCH 08/13] ring-buffer: rb_is_reader_page() can return boolean
Date: Tue, 03 Nov 2015 13:03:16 -0500	[thread overview]
Message-ID: <20151103180348.900854244@goodmis.org> (raw)
In-Reply-To: 20151103180308.542651732@goodmis.org

[-- Attachment #1: 0008-ring-buffer-rb_is_reader_page-can-return-boolean.patch --]
[-- Type: text/plain, Size: 997 bytes --]

From: Yaowei Bai <bywxiaobai@163.com>

Make rb_is_reader_page() return bool to improve readability due to this
particular function only using either true or false as its return value.

No functional change.
