% State of Art : Where we are with the Ext3 filesystem?
% Mingming Cao (cmm@us.ibm.com)
There has been a lot of ext3 filesystem
development work during the past two years
toward making ext3 an outstanding filesystem.
In this paper, we discuss some features like
directory indexing, block reservation and on-
line resizing, which have been accepted in the
mainline kernel recently. We also discuss
those features implemented but not yet
incorporated into the mainline kernel, such as
extent maps, delayed allocation and multiple
block allocation. We further include an
overview of implementation and performance
improvements for some of these features.
Finally, we review some features which are
still on the drawing board.
