+Subject: [PATCH v2] net: make napi_disable() symmetric with enable
+From: Jakub Kicinski <kuba@kernel.org>

+
+Commit 3765996e4f0b ("napi: fix race inside napi_enable") fixed
+an ordering bug in napi_enable() and made the napi_enable() diverge
+from napi_disable(). The state transitions done on disable are
+not symmetric to enable.
+
+There is no known bug in napi_disable() this is just refactoring.
+
+Eric suggests we can also replace msleep(1) with a more opportunistic
+usleep_range().
