Attached is a simple patch to the makefile line that builds convert.
It explicitly includes libcom_err, which is implicitly pulled in by
libext2fs. This fixes a what is called underlinking in this blog

I just had a bug reported (assigned to me) in the Gentoo Linux distro
about a missing option (-D) in btrfscrl. Looking into it, it
appears this feature is post the 0.19 tag of btrfs-progs. I would
like to get a more up-to-date btrfs-progs into Gentoo, but I would
like to follow the upstream
Here's a simple patch to replace gcc with $(CC) and make with
$(MAKE). This is required, for example, for Gentoo Linux ebuilds, and
it also eliminates a jobserver unavailable warning (make-related).

OK, I know Chris has described some block sharing. But I hate it.
If I copy resume to resume.save, it is because I want 2 copies
for safety. I don't want the fs to reduce it to 1 copy. And
reducing the duplicates is exactly opposite to Chris's paranoid

Josef's allocator fix is on the list because we currently fall over in

Chris, does it oops, or just get very slow? Does 0.15 do the same?

Focusing on the dd test, it looks like random corruption in the FS
metadata. I see you've got gentoo i386 and a 2.6.24 kernel, are there
any other patches in that kernel?
I have used Gentoo's 2.4.26 with

We're very concerned about data integrity. With btrfs everything is
checksummed at the logical level. This allows you to detect data
corruption, repair bad blocks using redundant, good copies, perform
data scrubbing, etc.
That's the main reason I am interesting in
