NTFS debugging support


Linux Kernel Configuration
└─>File systems
└─>DOS/FAT/NT Filesystems
└─>NTFS debugging support
In linux kernel since version 2.6.20 (release Date: 2007-02-04)  
If you are experiencing any problems with the NTFS file system, say
Y here. This will result in additional consistency checks to be
performed by the driver as well as additional debugging messages to
be written to the system log. Note that debugging messages are
disabled by default. To enable them, supply the option debug_msgs=1
at the kernel command line when booting the kernel or as an option
to insmod when loading the ntfs module. Once the driver is active,
you can enable debugging messages by doing (as root):
echo 1 > /proc/sys/fs/ntfs-debug
Replacing the "1" with "0" would disable debug messages.

If you leave debugging messages disabled, this results in little
overhead, but enabling debug messages results in very significant
slowdown of the system.

When reporting bugs, please try to have available a full dump of
debugging messages while the misbehaviour was occurring.
