New compiler warnings that I noticed when building a patchset based
on recent Fedora kernel:
fs/cifs/cifssmb.c: In function âCIFSSMBSetFileSizeâ:
fs/cifs/cifssmb.c:4813:8: warning: variable âdata_offsetâ set but not used
[-Wunused-but-set-variable]

fs/cifs/file.c: In function âcifs_iovec_writeâ:
fs/cifs/file.c:1740:9: warning: passing argument 6 of âCIFSSMBWrite2â from
incompatible pointer type [enabled by default]
fs/cifs/cifsproto.h:337:12: note: expected âunsigned int *â but argument is
of type âsize_t *â
fs/cifs/readdir.c: In function âcifs_readdirâ:
fs/cifs/readdir.c:767:23: warning: variable âcifs_sbâ set but not used
[-Wunused-but-set-variable]
fs/cifs/cifs_dfs_ref.c: In function âcifs_dfs_d_automountâ:
fs/cifs/cifs_dfs_ref.c:342:2: warning: ârcâ may be used uninitialized in
this function [-Wuninitialized]
fs/cifs/cifs_dfs_ref.c:278:6: note: ârcâ was declared here
