[lustre-devel] [PATCH 07/26] obdclass: use kernel types for kernel code

From: James Simmons <jsimmons@infradead.org>

Subject: [lustre-devel] [PATCH 07/26] obdclass: use kernel types for kernel code
Date: Thu, 31 Jan 2019 12:19:11 -0500	[thread overview]
Message-ID: <1548955170-13456-8-git-send-email-jsimmons@infradead.org> (raw)
In-Reply-To: <1548955170-13456-1-git-send-email-jsimmons@infradead.org>

Lustre obdclass code was originally both a user land and kernel
implementation. The source contains many types of the form __u32
but since this is mostly kernel code change the types to kernel
internal types.
