From mboxrd@z Thu Jan 1 00:00:00 1970 Return-Path: Return-Path: From: Josef Bacik To: axboe@kernel.dk, nbd-general@lists.sourceforge.net, linux-block@vger.kernel.org, kernel-team@fb.com Subject: [PATCH] nbd: set the max segment size to UINT_MAX Date: Tue, 18 Apr 2017 16:22:51 -0400 Message-Id: <1492546971-2682-1-git-send-email-jbacik@fb.com> List-ID: NBD doesn't care about limiting the segment size, let the user push the largest bio's they want. This allows us to control the request size solely through max_sectors_kb.
