void* _stp_alloc ( size_t len ) [inline]
+
+ + + + + +
+ + + +
+Allocates memory within a probe. +
+This is used for small allocations from within a running probe where the process cannot sleep.
Parameters:
+ + +
len Number of bytes to allocate.
+
+
Returns:
a valid pointer on success or NULL on failure.
+
Bug:
Currently uses kmalloc (GFP_ATOMIC).

Parameters:
+ + +
len Number of bytes to allocate.

void* _stp_valloc ( size_t len ) [inline]
+
+ + + + + +
+ + + +
+Allocates and clears memory outside a probe. +
+This is typically used in the module initialization to allocate new maps, lists, etc.
Parameters:
+ + +
len Number of bytes to allocate.
+
+
Returns:
a valid pointer on success or NULL on failure.
