Subject: [PATCH AUTOSEL 4.19 15/43] pNFS: Ensure we do clear the return-on-close layout stateid on fatal errors
Date: Tue, 1 Oct 2019 12:42:43 -0400 [thread overview]
Message-ID: <20191001164311.15993-15-sashal@kernel.org> (raw)
In-Reply-To: <20191001164311.15993-1-sashal@kernel.org>
From: Trond Myklebust <trondmy@gmail.com>
[ Upstream commit 9c47b18cf722184f32148784189fca945a7d0561 ]
IF the server rejected our layout return with a state error such as
NFS4ERR_BAD_STATEID, or even a stale inode error, then we do want
to clear out all the remaining layout segments and mark that stateid
as invalid.
Fixes: 1c5bd76d17cca ("pNFS: Enable layoutreturn operation for...")
