[PATCH v3 0/1] man/man3/aligned_alloc.3: HISTORY: Document bogus specification from C11

[Alejandro Colomar <alx@kernel.org>]

Hi!

I've already pushed patches 1..13 from v2, as nobody raised concerns.
v3 only contains a signle patch.

I've updated it to also document the case of FreeBSD/jemalloc, as
reported by Seth.


Have a lovely day!
Alex
