Subject: bcachefs: target_congested -> get_random_u32_below()
X-Git-Tag: v6.14-rc7~26^2~1
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=69a5a13a22b1def29dce62b5b7c86e6098c20c68;p=thirdparty%2Flinux.git

bcachefs: target_congested -> get_random_u32_below()

get_random_u32_below() has a better algorithm than bch2_rand_range(),
it just didn't exist at the time.
