down/up() - semaphores; set/clear/test_bit()
|
The following features are almost not documented (AFAIK). semaphore locking with down() up() functions and the usage of them. The bit operations set_bit() clear_bit() and test_bit() are also missing usage information. Those functions are important for drivers programmers that should take care about SMP/resource locking. Please email me <erez@newplaces.com> refrences if you know about. The KHG is missing an example section. Each function in the Linux kernel should have an example page in the KGH. |
