kbuild: Automatically remove stale <linux/version.h> file (223c24a7) · Commits · 戴 / test

In 3.7, the file moved from include/linux/ to include/generated/uapi/linux/. The path in the #include directive remained the same for compatibility reasons, but this created a problem when bisecting. Commit (kbuild: unconditionally clobber include/linux/version.h on distclean) fixes this, provided the user does make distclean between builds. Better not rely on the user and delete the stale file each time make is invoked. Cc: Paul Gortmaker <paul.gortmaker@windriver.com> Cc: David Howells <dhowells@redhat.com> Signed-off-by:
