Didnt see this happen on linux-3.x. filter: sector=242983 inode=0 filter: sector=242991 inode=0 filter: sector=242999 inode=0 filter: sector=243007 inode=0 filter: sector=243015 inode=0 filter: sector=243023 inode=0 filter: sector=243031 inode=0 filter: sector=243039 inode=0 What are these request with inode number as 0 ? All the special inode numbers start from 1. http://lxr.linux.no/#linux+v2.6.32/include/linux/ext3_fs.h#L56 Regards. -- To unsubscribe from this list: send the line "unsubscribe linux-ext4" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
