   4 Subject: [PATCH 02/23] Staging: add TAINT_CRAP flag to drivers/staging modules
   5 Patch-mainline: 2.6.28
   6
   7 We need to add a flag for all code that is in the drivers/staging/
   8 directory to prevent all other kernel developers from worrying about
   9 issues here, and to notify users that the drivers might not be as good
  10 as they are normally used to.
  11
  12 Based on code from Andreas Gruenbacher and Jeff Mahoney to provide a
  13 TAINT flag for the support level of a kernel module in the Novell
  14 enterprise kernel release.
  15
  16 This is the code that actually modifies the modules, adding the flag to
  17 any files in the drivers/staging directory.
