Merge branch 'upstream' of git://git.infradead.org/users/pcmoore/audit
Pull audit fixes from Paul Moore: "Four patches to fix various problems with the audit subsystem, all are fairly small and straightforward. One patch fixes a problem where we weren't using the correct gfp allocation flags (GFP_KERNEL regardless of context, oops), one patch fixes a problem with old userspace tools (this was broken for a while), one patch fixes a problem where we weren't recording pathnames correctly, and one fixes a problem with PID based filters. In general I don't think there is anything controversial with this patchset, and it fixes some rather unfortunate bugs; the allocation flag one can be particularly scary looking for users" * 'upstream' of git://git.infradead.org/users/pcmoore/audit: audit: restore AUDIT_LOGINUID unset ABI audit: correctly record file names with different path name types audit: use supplied gfp_mask from audit_buffer in kauditd_send_multicast_skb audit: don't attempt to lookup PIDs when changing PID filtering audit rules
