PATCH v2 1/1 staging: greybus: Convert timers to use timer_setup()

In preparation for unconditionally passing the struct timer_list pointer to all timer callbacks, switch to using the new timer_setup() and from_timer() to pass the timer pointer explicitly.

Hmm. Then something is really broken in this driver, you obviously must never free the async operation which contains the timer while the timer is active.

see attached for update - with my Signed-off added.

The right thing to do here is to respin your patch from last year which converts the loopback driver to use the timeout handling in greybus core. Otherwise, I'm afraid you're not addressing the underlying bug.

Either way, Kees, please submit the operation.c conversion separately from the loopback one, as the latter is non-trivial.

Thanks,
Johan

I think once Kees' change is applied to operation.c and we convert the async stuff to operation.c's callbacks there ought to be no use of timers, linked lists of operations.

I'll probably need at least a day to look at that, so it'll be the weekend before I can really allocate time.

Hi,

I seem to have lost the thread of conversation a bit. What exactly remains that I should be doing here for timer conversions? (It sounded like it was already partially handled already?)

Trying again without top posting in html :(

Just pair the patch down to operation.c.

There's a separate change to loopback.c an old patch ARAIR that will subtract use of the timer from loopback.c so you can skip that bit.

Okay, cool. Since the operation.c change is trivial, I'll include it in the giant tree-wide patch that will (hopefully) land in -rc1.

I forgot to ask: will the patch for loopback.c that removes the timers get posted in the next couple days? I just want to make sure the timer conversions don't get blocked behind this.
