[PATCH] re-export cancel_rearming_delayed_workqueue

81ddef77 · James Bottomley <[email protected]> · 2005-04-16 15:23:59 -07:00

This was unexported by Arjan because we have no current users.

However, during a conversion from tasklets to workqueues of the parisc led
functions, we ran across a case where this was needed.  In particular, the
open coded equivalent of cancel_rearming_delayed_workqueue was implemented
incorrectly, which is, I think, all the evidence necessary that this is a
useful API.
