initializes.
__exit Exit code. Ignored for non-modular drivers.
-
- __devinit Device initialization code.
- Identical to __init if the kernel is not compiled
- with CONFIG_HOTPLUG, normal function otherwise.
- __devexit The same for __exit.
-
Tips on when/where to use the above attributes:
o The module_init()/module_exit() functions (and all
initialization functions called _only_ from these)
o Do not mark the struct pci_driver.
- o The ID table array should be marked __devinitconst; this is done
- automatically if the table is declared with DEFINE_PCI_DEVICE_TABLE().
-
- o The probe() and remove() functions should be marked __devinit
- and __devexit respectively. All initialization functions
- exclusively called by the probe() routine, can be marked __devinit.
- Ditto for remove() and __devexit.
-
- o If mydriver_remove() is marked with __devexit(), then all address
- references to mydriver_remove must use __devexit_p(mydriver_remove)
- (in the struct pci_driver declaration for example).
- __devexit_p() will generate the function name _or_ NULL if the
- function will be discarded. For an example, see drivers/net/tg3.c.
-
o Do NOT mark a function if you are not sure which mark to use.
Better to not mark the function than mark the function wrong.
