+Subject: [PATCH 06/29] afs: Remove DFlushDCache()
+
+The function DFlushDcache() is not referenced anywhere within the
+source tree.
+
+Remove the function DFlushDCache().
+
+The commit: 'disconnected-shadow-directory-fixes-20090121' (4045f3d535)
+removed the code reference to DFlushDCache() and the commit:
+"dir: Prototype and function name cleanup" (5ad1e6cb90) removed the
+function prototype.  The function was introduced in the commit:
+"disconnected-flush-before-shadowing-20090119" (e1cc987ea5).
+
+This function is flagged due to a missing prototype when building
+against a Linux 6.8 kernel (which sets the -Wmissing-declarations and
+-Wmissing-prototypes compiler flags as default). Linux 6.8 commit:
+ "Makefile.extrawarn: turn on missing-prototypes globally" (0fcb70851f).
+
+When building against a kernel with CONFIG_WERROR=y, the build fails.
