Personally, I think this is a great idea. It would allow people who need the low memory usage to transition over to the ext4 driver while keeping the memory usage low. In such a case, I would almost suggest making an alias for the ext4 module (extfs maybe?) as modprobe ext4 no_ext4 has the potential to significantly confuse people.On Tue, 1 Sep 2015 15:39:45 -0400 Austin S Hemmelgarn <ahferroin7@xxxxxxxxx> wrote:On 2015-09-01 06:29, Albino B Neto wrote:2015-08-31 19:31 GMT-03:00 Raymond Jennings <shentino@xxxxxxxxx>:I think also that we should remove the ext2 driver before we remove the ext3 driver.Yes. It is logical to remove the old ext2 drive, because there are more computers with ext3 that ext2. Ext2 is obsolete by existing technologies.NO, it is not logical. A vast majority of Android smartphones in the wild use ext2, as do a very significant portion of embedded systems that don't have room for the few hundred kilobytes of extra code that the ext4 driver has in comparison to ext2.Would it be possible to discard the code used for ext4 and ext3 features at module init time? So you could do something like: modprobe ext4 no_ext4 no_ext3 and all the space used by those functions would be freed and the filesystem driver would mark all the ext3/ext4 features as unsupported.
