From ebb16d0d1b326c252fef9f339a7322ee44ed104f Mon Sep 17 00:00:00 2001 From: Josef Bacik Date: Tue, 18 Apr 2017 16:22:51 -0400 Subject: nbd: set the max segment size to UINT_MAX 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.
