From: Josef Bacik Date: Thu, 20 Apr 2017 19:47:01 +0000 (-0400) Subject: nbd: set the max segments to USHRT_MAX X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=1cc1f17aab7e596d0a7373fc1ed11dbddfa82bc9;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git nbd: set the max segments to USHRT_MAX I lack the basic understanding of what segments mean, so we were being limited to 512kib requests even with higher max_sectors sizes set. Setting the maximum number of segments to unlimited allows us to actually have arbitrarily large IO's go through NBD.
