+Subject: [PATCH] VyOS: add inotify support for stackable filesystems
+ (overlayfs)
+
+As it stands at the moment, overlayfs doesn't have full support for
+inotify, and as such anything that relies on inotify currently has
+issues. The simplest method of demonstrating this is to tail a file
+(so tail -f /var/log/messages) and see that it doesn't follow changes
+in that file. This has been reported in a number of places, including
+Bug #882147 in Ubuntu. This patch is based on the version proposed by
+Li Jianguo in response to this bug, adding support for inotify in
+stackable filesystems.
+
+This commit provides a complete fix for the workaround implemented
+for bug #303, and will allow that commit to be reverted.
+
+Bug #425 http://bugzilla.vyos.net/show_bug.cgi?id=425
+

+From: Riku Voipio <riku.voipio@linaro.org>
+
+Perf is shipped in debian in linux-tools-$version package. Extend
+the existing to builddeb script to build perf if BUILD_TOOLS=y
+is added the make deb-pkg line
+
+Some features of this patch I'm uncomfortable with:
+
+1. Relative paths are resoved to absolute ones
+ Especially with separate O= buildd, perf build from tools/perf dir
+ fail.
+
+2. Unsetting LDFLAGS
+ make -> shell (builddeb) -> make expands variables. The LDFLAGS as
+ set by toplevel makefile are for kernel, so we just unset the flag
+ here.
+
+3. Replaces ubuntu/debian packages instead attempting to fit to
+ the linux-base/linux-tools-common frameworks. I think people who
+ want to run "make deb-pkg" for their kernels would rather keep this
+ simple.
+
+4. More tools than just perf could be built - unfortunately most
+ tools fail to have a working "install" target and/or else have
+ build process inconsistent with other tools. A topic for another
+ patch series.
