/*
|
|
* Emulate the behavior of utimensat(int fd, const char *name,
|
|
* const struct timespec times[2], int flag)
|
|
*
|
|
* Note that emulation methods that do not use the /proc filesystem are
|
|
* not MT safe. In the non-MT-safe case, we do:
|
|
*
|
|
* savewd()/fchdir()/open(name)/restorewd()
|
|
*
|
|
* Errors may force us to abort the program as our caller is not expected
|
|
* to know that we do more than a simple open() here and that the
|
|
* working directory may be changed by us.
