+Subject: [PATCH] basic: update CIFS magic
+
+Kernel commit dea2903719283c156b53741126228c4a1b40440f exposed (and
+renamed) CIFS_MAGIC_NUMBER as CIFS_SUPER_MAGIC along with
+SMB2_SUPER_MAGIC.
+
+This fixes the following build fail on current Fedora Rawhide:
+```
+../src/basic/meson.build:389:8: ERROR: Problem encountered: found unknown filesystem(s) defined in kernel headers:
+
+Filesystem found in kernel header but not in filesystems-gperf.gperf: CIFS_SUPER_MAGIC
+Filesystem found in kernel header but not in filesystems-gperf.gperf: SMB2_SUPER_MAGIC
