Hey.
Just a followup on this:
GPT and some others (e.g MD RAID) store data in the end of the device.
It's clear that when the fs is made inside a partition, this shouldn't
be seen (and thus TRIMmed) anyway... but can btrfs be installed e.g.
directly on the device while that continues to hold the GPT (by btrfs
simply always starting at some byte offset)?
If so, then one may possibly need to extend that patch for the end of
the device.
Cheers,
Chris.
