It is optimized for files that 20 are rarely modified. 21 Enabling this option builds the decompression support into the NTFS 22 module. 23 24config NTFS_DEBUG 25 bool "NTFS debugging support" 26 depends on NTFS_FS 27 help 28 If you are experiencing any problems with the NTFS file system, say 29 Y here. This will result in additional consistency checks to be 30 performed by the driver as well as additional debugging messages to 31 be written to the system log. Note that debugging messages are 32 disabled by default. To enable them, supply the option debug_msgs=1 33 at the kernel command line when booting the kernel or as an option 34 to insmod when loading the ntfs module. Once the driver is active, 35 you can enable debugging messages by doing (as root): 36 echo 1 > /proc/sys/fs/ntfs-debug 37 Replacing the "1" with "0" would disable debug messages. 38 39 If you leave debugging messages disabled, this results in little 40 overhead, but enabling debug messages results in very significant 41 slowdown of the system. 42 43 When reporting bugs, please try to have available a full dump of 44 debugging messages while the misbehaviour was occurring. 45 46config NTFS_FS_POSIX_ACL 47 bool "NTFS POSIX Access Control Lists" 48 depends on NTFS_FS 49 select FS_POSIX_ACL 50 help 51 POSIX Access Control Lists (ACLs) support additional access rights 52 for users and groups beyond the standard owner/group/world scheme. 53 54 This option enables ACL support for ntfs, providing functional parity 55 with ntfs3 drivier. 56 57 NOTE: this is linux only feature. Windows will ignore these ACLs. 58 59 If you don't know what Access Control Lists are, say N. 60
