[PATCH net-next v3] nfp: Convert timeouts to secs_to_jiffies()
Posted by Easwar Hariharan 1 year ago
Commit b35108a51cf7 ("jiffies: Define secs_to_jiffies()") introduced
secs_to_jiffies(). As the value here is a multiple of 1000, use
secs_to_jiffies() instead of msecs_to_jiffies to avoid the multiplication.

This is converted using scripts/coccinelle/misc/secs_to_jiffies.cocci with
the following Coccinelle rules:

@@ constant C; @@

- msecs_to_jiffies(C * 1000)
+ secs_to_jiffies(C)

@@ constant C; @@

- msecs_to_jiffies(C * MSEC_PER_SEC)
+ secs_to_jiffies(C)

This patch is pulled out from v2 [1] of my series to convert users of
msecs_to_jiffies() that need seconds-denominated timeouts to the new
secs_to_jiffies() API in include/linux/jiffies.h to send with the
net-next prefix as suggested by Christophe Leroy.

It may be possible to use prefixes for some patches but not others with b4
(that I'm using to manage the series as a whole) but I didn't find such
in the help. v3 of the series addressing other review comments is here:

It's not super clear to me which patch is handled where and through which tree
at the moment, but looks like this is a network driver change scoped to the
netdev tree, so makes sense to me to add sign-off here. Thanks for applying
this to the nfp driver.

Thanks for the review! All netdev patches will be handled via the netdev
tree, separately from the series, per Jakub's request. There are patches
for gve and ath11k that will also be pulled out from the series and go
through netdev. I'll send a v4 series to netdev including your
Reviewed-by for this patch.

Thanks,
Easwar

No need to repost this patch. Tooling will pick up Louis' tag.
