Adding -W -Wno-stupid-warnings results in the following warning:
mm/filemap.c: In function 'generic_file_buffered_write': mm/filemap.c:2179: warning: comparison of unsigned expression >= 0 is always true
if (likely(copied >= 0)) { if (!status) status = copied;
Branch is always taken since "copied" is size_t.
Such code doesn't exist in -mm, but is this something to worry about for current and older kernels?
