hfsplus: pretend special inodes as regular files

0 Fork 0

[ Upstream commit ed8889ca21b6ab37bc1435c4009ce37a79acb9e6 ]

Since commit af153bb63a33 ("vfs: catch invalid modes in may_open()")
requires any inode be one of S_IFDIR/S_IFLNK/S_IFREG/S_IFCHR/S_IFBLK/
S_IFIFO/S_IFSOCK type, use S_IFREG for special inodes.
