  NFS: remove set but not used variable 'mapping' (2019-08-27 10:24:56 -0400)

----------------------------------------------------------------
NFS client bugfixes for Linux 5.3

Highlights include:

Stable fixes:
- Fix a page lock leak in nfs_pageio_resend()
- Ensure O_DIRECT reports an error if the bytes read/written is 0
- Don't handle errors if the bind/connect succeeded
- Revert "NFSv4/flexfiles: Abort I/O early if the layout segment was invalidat
ed"

Bugfixes:
- Don't refresh attributes with mounted-on-file information
- Fix return values for nfs4_file_open() and nfs_finish_open()
- Fix pnfs layoutstats reporting of I/O errors
- Don't use soft RPC calls for pNFS/flexfiles I/O, and don't abort for
  soft I/O errors when the user specifies a hard mount.
- Various fixes to the error handling in sunrpc
- Don't report writepage()/writepages() errors twice.
