From: Sagi Grimberg Date: Wed, 26 Feb 2020 00:42:27 +0000 (-0800) Subject: nvmet-tcp: fix maxh2cdata icresp parameter X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=9cda34e37489244a8c8628617e24b2dbc8a8edad;p=linux.git nvmet-tcp: fix maxh2cdata icresp parameter MAXH2CDATA is not zero based. Also no reason to limit ourselves to 1M transfers as we can do more easily. Make this an arbitrary limit of 16M.
