From mboxrd@z Thu Jan 1 00:00:00 1970 Return-Path: From: Lars-Peter Clausen To: Jonathan Cameron Cc: linux-iio@vger.kernel.org, Lars-Peter Clausen Subject: [PATCH v2 4/4] iio:kfifo: Set update_needed to false after allocating a new buffer Date: Tue, 15 Oct 2013 10:30:30 +0200 Message-Id: <1381825830-25581-4-git-send-email-lars@metafoo.de> In-Reply-To: <1381825830-25581-1-git-send-email-lars@metafoo.de> References: <1381825830-25581-1-git-send-email-lars@metafoo.de> List-ID: update_needed is used to decide whether the kfifo buffer needs to be re-allocated. It is set to true whenever the size of the buffer is changed. It is never set to false though, causing the buffer to always be re-allocated. Setting update_needed to false after the new buffer has been allocated fixes the problem.
