>Description:
Since somewhere in October (on 5.0-CURRENT) files on a NTFS filesystem cannot be read, although directory listings can be made. The error returned is "Inappropriate ioctl for device"
>How-To-Repeat:
Mount a NTFS partition, try to cat(1) a file.
>Fix:
ntfs_bypass() always returns ENOTTY (Inappropriate ioctl for device), and is only used for vop_default_desc. Looking at other fs's I came to the conclusion that they almost all use vop_defaultop() for vop_default_desc, or code that is exactly the same. Hence the following patch, which works fine for me.
