Subject: ccan/io: keep always pointers to plans, not a linked list.
X-Git-Url: http://git.ozlabs.org/?p=ccan;a=commitdiff_plain;h=a5881c0deb210f56c2095366ae6cdabd5230d68d;hp=a5881c0deb210f56c2095366ae6cdabd5230d68d

ccan/io: keep always pointers to plans, not a linked list.

Duplex io_conns can be in the always list twice, and it was a source
of bugs, but I didn't want to add a second list_node.  Since there are
not many always at once, it's better (and more space-efficient) to use
a simple pointer array.
