Hi Al, After merging the vfs tree, today's linux-next build (x86_64 allmodconfig) failed like this: samples/statx/test-fsinfo.c:26:10: fatal error: linux/fsinfo.h: No such file or directory #include ^~~~~~~~~~~~~~~~ Caused by commit 90b413cb970a ("vfs: syscall: Add fsinfo() to query filesystem information") I guess that headers_install (or whatever its called) has not bee run before the sample code is built. I have applied the following patch for today: From: Stephen Rothwell Date: Mon, 6 Aug 2018 10:29:34 +1000 Subject: [PATCH] vfs: don;t build new sample programs yet It seems that headers_install is not done before the samples are build so some needed include files are not in the right place.
