vfs: Introduce logging functions
Introduce a set of logging functions through which informational messages, warnings and error messages incurred by the mount procedure can be logged and, in a future patch, passed to userspace instead by way of the filesystem configuration context file descriptor. There are four functions: (1) infof(const char *fmt, ...); Logs an informational message. (2) warnf(const char *fmt, ...); Logs a warning message. (3) errorf(const char *fmt, ...); Logs an error message. (4) invalf(const char *fmt, ...); As errof(), but returns -EINVAL so can be used on a return statement.
