ntfs: logging clean-up
- Convert spinlock/static array to va_format (inspired by Joe Perches
help on previous logging patches).
- Convert printk(KERN_ERR to pr_warn in __ntfs_warning.
- Convert printk(KERN_ERR to pr_err in __ntfs_error.
- Convert printk(KERN_DEBUG to pr_debug in __ntfs_debug. (Note that
__ntfs_debug is still guarded by #if DEBUG)
- Improve !DEBUG to parse all arguments (Joe Perches).
- Sparse pr_foo() conversions in super.c
NTFS, NTFS-fs prefixes as well as 'warning' and 'error' were removed :
pr_foo() automatically adds module name and error level is already
specified.
