    Work around bug in CIFS and vboxsf file systems. · 9fe43ff6
    Paul Eggert authored
    The bug was observed on Ubuntu operating inside a virtual machine,
    editing files mounted via CIFS or vboxsf from the MS Windows 7 host.
    The workaround introduces a race condition on non-buggy hosts,
    but it's an unlikely race and anyway there's a nearly identical
    nearby race that can't be fixed.
    * fileio.c (valid_timestamp_file_system, timestamp_file_system):
    New static vars.
    (Fwrite_region): Test for file system time stamp bug.
    (init_fileio): New function.
    * lisp.h (init_fileio): Declare it.
    * emacs.c (main): Call it.
    Fixes: debbugs:13149
