3.10-stable review patch. If anyone has any objections, please let me know. ------------------ From: Valdis Kletnieks <Valdis.Kletnieks@xxxxxx> commit d4bf205da618bbd0b038e404d646f14e76915718 upstream. The pstore filesystem still creates duplicate filename/inode pairs for some pstore types. Add the id to the filename to prevent that.
