Subject: [PATCH 5.2 075/124] NFS: remove set but not used variable mapping
From: YueHaibing <yuehaibing@...wei.com>
[ Upstream commit 99300a85260c2b7febd57082a617d1062532067e ]
Fixes gcc '-Wunused-but-set-variable' warning:
fs/nfs/write.c: In function nfs_page_async_flush:
fs/nfs/write.c:609:24: warning: variable mapping set but not used [-Wunused-but-set-variable]
It is not use since commit aefb623c422e ("NFS: Fix
writepage(s) error handling to not report errors twice")
