[PATCH AUTOSEL 4.9 07/27] NFS: Fix initialisation of I/O result struct in nfs_pgio_rpcsetup

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Trond Myklebust <trond.myklebust@xxxxxxxxxxxxxxx>

[ Upstream commit 17d8c5d145000070c581f2a8aa01edc7998582ab ]

Initialise the result count to 0 rather than initialising it to the
argument count. The reason is that we want to ensure we record the
I/O stats correctly in the case where an error is returned (for
instance in the layoutstats).
