Since deduplication potentially has to read in all the pages in both files in order to compare the contents, cap the deduplication request length at MAX_RW_COUNT/2 (roughly 1GB) so that we have /some/ upper bound on the request length and can't just lock up the kernel forever. Found by running generic/304 after commit 1ddae54555b62 ("common/rc: add missing 'local' keywords"). Reported-by:<matorola@gmail.com> Signed-off-by:
