Subject: NFSv4.1/pnfs: Fixup an lo->plh_block_lgets imbalance in layoutreturn
From: Trond Myklebust <trond.myklebust@xxxxxxxxxxxxxxx>
commit 1a093ceb053832c25b92f3cf26b957543c7baf9b upstream.
Since commit 2d8ae84fbc32, nothing is bumping lo->plh_block_lgets in the
layoutreturn path, so it should not be touched in nfs4_layoutreturn_release
either.
Fixes: 2d8ae84fbc32 ("NFSv4.1/pnfs: Remove redundant lo->plh_block_lgets...")
