[PATCH] x86, hpet.c: Changed type of field work of hpet_work_struct (delayed_work to work_struct)
Hi Venki, here the new patch with the changes you requested. Thanks. The hpet_work_struct has a delayed_work (field work), but it doesn't use delay. So this field type was changed for work_struct, and its utilizations as delayed_work were adapted to work_struct. Signed-off-by: Leonardo de Sá Alt <leonardoa... 16 Jun 2010 11:03

perf/perf_events: misleading number of samples due to mmap()
