Cool, another gentooer! =:^)

FWIW, I've been doing my own kernels (mainline) since back on mandrake a 
decade ago, and I just changed up my scripts a bit when I switched to 
gentoo.  Then later on I changed them up a bit more to be able to run git 
kernels.  These days I normally first try (and switch to if no serious 
bugs) to the dev kernel around -rc2 or so, by which point I figure 
anything likely to eat my system for breakfast should be either worked 
thru, or at least news of it available.  As a non-dev, it's very cool 
being able to spot and report bugs, possibly bisecting to a specific 
commit, and watch them get fixed before general kernel release. Just one 
way I as a non-dev can contribute back.  =:^)

To take care of packages that depend on a kernel package, I used to have 
a kernel (gentoo-sources-2.6.9999 or some such, back then, now of course 
it'd be 3.9999) in package.provided, but these days I don't even need 
that. =:^)

btrfs-progs-9999 is available, but as a live package, it's masked in 
keeping with gentoo policy.  So to get it you'd need to unmask it.

But 0.20_rc1_p358 shouldn't be /too/ far back.  In fact, I'm guessing the 
p-number is the (serialized) patch sequence number indicating the number 
of commits forward from the rc1 tag.  And on the (locally unmasked) -9999 
version here, a git describe --tags gives me

v0.20-rc1-358-g194aa4a

... so 0.20_rc1_p358 is very likely identical to the live version at this 
point, and it makes no difference, except that the non-live version is a 
stable snapshot instead of a version that might change every time you 
merge it, if upstream has done any further commits.

So btrfs-progs-0.20_rc1_p358 should be fine.  And you were updating 
kernel to 3.11.2, so that should be fine by the time you read this, as 
well. =:^)
