audit_log_start — obtain an audit buffer


struct audit_buffer * audit_log_start (struct audit_context * ctx,
 gfp_t gfp_mask,
 int type);


struct audit_context * ctx

audit_context (may be NULL)

gfp_t gfp_mask

type of allocation

int type

audit message type


Returns audit_buffer pointer on success or NULL on error.

Obtain an audit buffer. This routine does locking to obtain the audit buffer, but then no locking is required for calls to audit_log_*format. If the task (ctx) is a task that is currently in a syscall, then the syscall is marked as auditable and an audit record will be written at syscall exit. If there is no associated task, then task context (ctx) should be NULL.
