NAME
       audit_log_start - obtain an audit buffer

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

ARGUMENTS
       ctx
	   audit_context (may be NULL)

       gfp_mask
	   type of allocation

       type
	   audit message type

DESCRIPTION
       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.
