From mboxrd@z Thu Jan 1 00:00:00 1970 From: Nishanth Aravamudan Subject: [PATCH] Add ssleep_interruptible() Date: Mon, 1 Nov 2004 12:07:49 -0800 Message-ID: <20041101200749.GF1730@us.ibm.com> References: Mime-Version: 1.0 Content-Type: text/plain; charset=us-ascii; format=flowed Cc: netdev@oss.sgi.com, jgarzik@pobox.com, linux-kernel@vger.kernel.org, kernel-janitors@lists.osdl.org Return-path: To: janitor@sternwelten.at Content-Disposition: inline In-Reply-To: Sender: netdev-bounce@oss.sgi.com Errors-to: netdev-bounce@oss.sgi.com List-Id: netdev.vger.kernel.org Description: Adds ssleep_interruptible() to allow longer delays to occur in TASK_INTERRUPTIBLE, similarly to ssleep(). To be consistent with msleep_interruptible(), ssleep_interruptible() returns the remaining time left in the delay in terms of seconds. This required dividing the return value of msleep_interruptible() by 1000, thus a cast to (unsigned long) to prevent any floating point issues.
