[PATCH 1/5] WorkStruct: Separate delayable and non-delayable events. [try #2]

David Howells
2006-11-22T13:06:19Z

Separate delayable work items from non-delayable work items be splitting them
into a separate structure (delayed_work), which incorporates a work_struct and
the timer_list removed from work_struct.

The work_struct struct is huge, and this limits it's usefulness. On a 64-bit
architecture it's nearly 100 bytes in size. This reduces that by half for the
non-delayable type of event.
