[PATCH 6/6] get_unmapped_area remove extra check for TASK_SIZE

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



architecture specific and generic arch_get_unmapped_area() and
arch_get_unmapped_area_topdown() check for TASK_SIZE before
MAP_FIXED.

It is safe to remove check for TASK_SIZE in get_unmapped_area().
