The kernel defines for expire type such as an immediate expire
|
|
|
beb904 |
shoule be used to clearify what is being requested.
|
|
|
beb904 |
|
|
|
beb904 |
AUTOFS_EXP_IMMEDIATE corresponds to a SIGUSR1 prune operation.
|
|
|
beb904 |
|
|
|
beb904 |
AUTOFS_EXP_FORCE corresponds to an expire type not yet implemented in
|
|
|
beb904 |
the kernel, a SIGUSR2 forced expire. Define it in our internal autofs
|
|
|
beb904 |
kernel include file, the kernel will ignore it if it doesn't support it.
|
|
|
beb904 |
|
|
|
beb904 |
AUTOFS_EXP_LEAVES is no longer used in autofs version 5.
|
|
|
beb904 |
|
|
|
beb904 |
Finally add a define AUTOFS_EXP_NORMAL to indicate we're perfoming a
|
|
|
beb904 |
normal expire.
