Hello, I am starting with ext4 development, so I have lot's of questions =) 1> About ext4 feature FLEX_BG, I see that it merges multiple groups in 1 group, but I wonder how this makes sense... In ext3 did each block group contain always 1 block? If not, then how many? And if not, how does that differ from FLEX_BG? 2> I see that the number of groups inside a flexible group is given by 2^sb.s_log_groups_per_flex but: a> Every single group is a flexible group or some are and some now? b> This number is the same for all flexible groups? 3> Could anyone be kind enough to post the full path which is done to find data in a given file? I already found inode.i_block .... wonder what are the other links between things, like for example between a group and inodes, etc... thanks, Felipe Monteiro de Carvalho PS: I need to restrict each line to 80 chars because of gmane, sorry for that =( -- 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
