Subject: [PATCH] Revert "eloop: Allow eloop to process all fds returned from
|
||||
poll(2)"
|
||||
|
||||
This stops dumping leases when privsep is compiled out.
|
||||
This change works fine on master, but we also have eloop using
|
||||
more of a native poll(2) style interface.
|
||||
Easier for now to just revert this on the dhcpcd-9 branch.
|
||||
|
||||
This reverts commit fe2b82eec25da908c3a1a71c2dc2402d9ff70e31.
