Subject: [PATCH] logind: process session/inhibitor fds at higher priority
fa0155
fa0155
Let's make sure we process session and inhibitor pipe fds (that signal
fa0155
sessions/inhibtors going away) at a higher priority
fa0155
than new bus calls that might create new sessions or inhibitors. This helps
fa0155
ensuring that the number of open sessions stays minimal.
