charset="us-ascii" Content-Transfer-Encoding: 7bit Sender: devel-bounces@openvz.org Errors-To: devel-bounces@openvz.org Applied with two small changes on commit, no need to resend. 1. Added Fixes: 6ddad5a4d226 ("dm-ploop: Add ploop target driver") 2. Changed the message of the new check in ploop_resize(). After the patch the function prints the same text from two different checks: } else if (SEC_TO_CLU(ploop, new_sectors) >= U32_MAX - 2) { DMWARN("resize: too large size is requested"); return -EINVAL; ... nr_bat_entries = SEC_TO_CLU(ploop, new_sectors); nr_bat_clusters = ploop_nr_bat_clusters(ploop, nr_bat_entries); if ((u64)nr_bat_clusters + nr_bat_entries > PLOOP_MAX_HB_NR) { DMWARN("resize: too large size is requested"); return -EINVAL; } Both checks are needed: the first one runs on sector_t and guards the u32 truncation of nr_bat_entries, the second one bounds hb_nr. But with the same text the log does not tell which one fired, and the first check looks redundant next to the second one. So the new check now says what does not fit, matching "Too large BAT" in ploop_setup_metadata(): DMWARN("resize: too large BAT"); -- Best regards, Konstantin Khorenko, Virtuozzo Linux Kernel Team _______________________________________________ Devel mailing list Devel@openvz.org https://lists.openvz.org/mailman/listinfo/devel
