Hi Mingming, This is the updated block reservation patch. This patch can replace the ext4-block-reservation.patch in the patch queue. I think we should fold all the below patches into one ext4_block_reservation_fix3.patch ext4-block-reservation.patch ext4_rebalance_reservation_invariant_checking_fix.patch ext4_reserve_global_return_error_fix.patch If yes i can redo the patch again. NOTE: The patch follows this mail. -aneesh - To unsubscribe from this list: send the line "unsubscribe linux-ext4" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
