Randy, >> Mar 23 17:40:10 hades kernel: sd 0:0:0:0: [sda] Optimal transfer size 0 >> bytes < PAGE_SIZE (4096 bytes) We're just trying to weed out the devices that report garbage in this field. But of course none of the devices I tested with put 0 in there. >> Does it really belong in an LTS kernel? The patch does fix problems for devices that report a nonsensical value. But it is a regression that it now prints a warning for devices that don't report an optimal I/O size at all. Sorry about that. Will fix tomorrow! -- Martin K. Petersen Oracle Linux Engineering
