From mboxrd@z Thu Jan 1 00:00:00 1970 From: Tatyana Brokhman Subject: [RFC/PATCH 0/2] Adding support for urgent requests handling Date: Sun, 16 Sep 2012 12:06:40 +0300 Message-ID: <1347786402-7339-1-git-send-email-tlinder@codeaurora.org> Return-path: Sender: linux-mmc-owner@vger.kernel.org To: axboe@kernel.dk Cc: linux-mmc@vger.kernel.org, linux-arm-msm@vger.kernel.org, Tatyana Brokhman List-Id: linux-arm-msm@vger.kernel.org This patch set adds support in block & elevator layers for handling urgent requests. Urgent request notification passed to underlying driver (eMMC for example) and causes interruption of low priority current request in order to execute the urgent one. The interrupted request is inserted back to the scheduler's internal data structures.
