Subject: [PATCH AUTOSEL 4.9 04/23] ceph: return ceph_mdsc_do_request() errors from __get_parent()
Date: Sat, 18 Apr 2020 10:43:46 -0400 [thread overview]
Message-ID: <20200418144405.10565-4-sashal@kernel.org> (raw)
In-Reply-To: <20200418144405.10565-1-sashal@kernel.org>
From: Qiujun Huang <hqjagain@gmail.com>
[ Upstream commit c6d50296032f0b97473eb2e274dc7cc5d0173847 ]
Return the error returned by ceph_mdsc_do_request(). Otherwise,
r_target_inode ends up being NULL this ends up returning ENOENT
regardless of the error.
