From mboxrd@z Thu Jan 1 00:00:00 1970 From: James Simmons Date: Tue, 2 Jun 2020 20:59:43 -0400 Subject: [lustre-devel] [PATCH 04/22] lustre: ptlrpc: change LONG_UNLINK to PTLRPC_REQ_LONG_UNLINK In-Reply-To: <1591146001-27171-1-git-send-email-jsimmons@infradead.org> References: <1591146001-27171-1-git-send-email-jsimmons@infradead.org> Message-ID: <1591146001-27171-5-git-send-email-jsimmons@infradead.org> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: lustre-devel@lists.lustre.org From: Mr NeilBrown The name "LONG_UNLINK" is vague and generic. Change it to PTLRPC_REQ_LONG_UNLINK to make it clear it is about requests taking a long time, and of interest to PTLRPC.
