[PATCH 0/2] firewire: core: use helper macro to calculate jiffies count

Posted by Takashi Sakamoto 2 weeks, 3 days ago

Hi,

In this subsystem, all types of timeouts are managed using kernel timer
wheel, thus they are based on jiffies grain. Some macros are available
to calculate jiffies count, and they have some advantages, For example,
no need to access to HZ macro or jiffies itself directly.

This patchset replaces several lines with these macros.

Takashi Sakamoto (2):
  firewire: core: use helper macros instead of direct access to HZ
  firewire: core: use helper macro to compare against current jiffies
