Eh, I actually wanted to send this a while ago, sorry

I tested this a bit by compiling glibc on  2.4GB partition. It seems to
work quite well at first, but after a while, I got a couple of errors.
Most of them were plain freezes or Resource lost. I also had quite some
filesystem corruption when (forcibly) checking the file system. After
reverting the patch and to a smaller partition, I was able to build
glibc without problems :-/

This is the meaningful error message I encountered(transcribed):

ext2fs.static: ../../ext2fs/pager.c:1045: disk_cache_block_ref:
        Assertion '0 <= block && block <= store->size >>
        log2_block_size' failed.

Also, I noticed that I am no longer able to mount my (rather small) root
GNU/Linux partition, as it has less than 4kb blocks. I don't remember
specifying anything special when I install GNU/Linux, so I wonder
whether this is expected to be fixed/resolved?

Did you try to get it applied upstream?
