Subject: [lustre-devel] [PATCH 01/18] lnet: restore an maximal fragments count
Date: Wed,  1 Jul 2020 20:04:41 -0400	[thread overview]
Message-ID: <1593648298-10571-2-git-send-email-jsimmons@infradead.org> (raw)
In-Reply-To: <1593648298-10571-1-git-send-email-jsimmons@infradead.org>

From: Alexey Lyashkov <c17817@cray.com>

Lowering a number of fragments blocks a connection from older clients
who wants to use 256 fragments to transfer. Let's restore this number
to the original value.

Fixes: ab7e089b8eda ("lustre: lnet: make LNET_MAX_IOV dependent on page size")

Cray-bug-id: LUS-8139
WC-bug-id: https://jira.whamcloud.com/browse/LU-10157
