Subject: smb: client: report correct st_size for SMB and NFS symlinks
From: Paulo Alcantara <pc@xxxxxxxxxxxxx>
commit 9d63509547a940225d06d7eba1dc412befae255d upstream.
We can't rely on FILE_STANDARD_INFORMATION::EndOfFile for reparse
points as they will be always zero. Set it to symlink target's length
as specified by POSIX.
This will make stat() family of syscalls return the correct st_size
for such files.
