This will result in additional consistency checks to be 19 performed by the driver as well as additional debugging messages to 20 be written to the system log. Note that debugging messages are 21 disabled by default. To enable them, supply the option debug_msgs=1 22 at the kernel command line when booting the kernel or as an option 23 to insmod when loading the ntfs module. Once the driver is active, 24 you can enable debugging messages by doing (as root): 25 echo 1 > /proc/sys/fs/ntfs-debug 26 Replacing the "1" with "0" would disable debug messages. 27 28 If you leave debugging messages disabled, this results in little 29 overhead, but enabling debug messages results in very significant 30 slowdown of the system. 31 32 When reporting bugs, please try to have available a full dump of 33 debugging messages while the misbehaviour was occurring. 34 35config NTFS_FS_POSIX_ACL 36 bool "NTFS POSIX Access Control Lists" 37 depends on NTFS_FS 38 select FS_POSIX_ACL 39 help 40 POSIX Access Control Lists (ACLs) support additional access rights 41 for users and groups beyond the standard owner/group/world scheme. 42 43 This option enables ACL support for ntfs, providing functional parity 44 with ntfs3 drivier. 45 46 NOTE: this is linux only feature. Windows will ignore these ACLs. 47 48 If you don't know what Access Control Lists are, say N. 49
