[PATCH] get rid of AVC_PATH postponed treatment
Selinux folks had been complaining about the lack of AVC_PATH records when audit is disabled. I must admit my stupidity - I assumed that avc_audit() really couldn't use audit_log_d_path() because of deadlocks (== could be called with dcache_lock or vfsmount_lock held). Shouldn't have made that assumption - it never gets called that way. It _is_ called under spinlocks, but not those. Since audit_log_d_path() uses ab->gfp_mask for allocations, kmalloc() in there is not a problem. IOW, the simple fix is sufficient: let's rip AUDIT_AVC_PATH out and simply generate pathname as part of main record. It's trivial to do.
