Subject: gdb/linux-fork: simplify one_fork_p
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=fa47e4463ab4ee4ddc7858ab11063c7965b232ac;p=binutils-gdb.git

gdb/linux-fork: simplify one_fork_p

Unless I'm missing something, this function is a complicated way of
saying "fork_list.size () == 1".

gdb/ChangeLog:

	* linux-fork.c (one_fork_p): Simplify.
