| help | |
| NTFS is the file system of Microsoft Windows NT, 2000, XP and 2003. | |
| This allows you to mount devices formatted with the ntfs file system. | |
| To compile this as a module, choose M here: the module will be called | |
| ntfs. | |
| config NTFS_FS_WOF_COMPRESSION | |
| bool "NTFS Windows system compression support" | |
| depends on NTFS_FS | |
| help | |
| Enable read support for Windows system-compressed files. | |
| Windows more aggressively compresses system files such as binaries | |
| and DLLs using system compression. It is optimized for files that | |
| are rarely modified. | |
| Enabling this option builds the decompression support into the NTFS | |
| module. | |
| config NTFS_DEBUG | |
| bool "NTFS debugging support" | |
| depends on NTFS_FS | |
| help | |
| 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. | |
| config NTFS_FS_POSIX_ACL | |
| bool "NTFS POSIX Access Control Lists" | |

| select FS_POSIX_ACL | |
| help | |
| POSIX Access Control Lists (ACLs) support additional access rights | |
| for users and groups beyond the standard owner/group/world scheme. | |
| This option enables ACL support for ntfs, providing functional parity | |
| with ntfs3 drivier. | |
| NOTE: this is linux only feature. Windows will ignore these ACLs. | |
| If you don't know what Access Control Lists are, say N. |
