21 | /* | ||
22 | * XFS arguments structure, constructed from the arguments we | ||
23 | * are passed via the mount system call. | ||
24 | * | ||
25 | * NOTE: The mount system call is handled differently between | ||
26 | * Linux and IRIX. In IRIX we worked work with a binary data | ||
27 | * structure coming in across the syscall interface from user | ||
28 | * space (the mount userspace knows about each filesystem type | ||
29 | * and the set of valid options for it, and converts the users | ||
30 | * argument string into a binary structure _before_ making the | ||
31 | * system call), and the ABI issues that this implies. | ||
32 | * | ||
33 | * In Linux, we are passed a comma separated set of options; | ||
34 | * ie. a NULL terminated string of characters. Userspace mount | ||
35 | * code does not have any knowledge of mount options expected by | ||
36 | * each filesystem type and so each filesystem parses its mount | ||
37 | * options in kernel space. | ||
38 | * | ||
39 | * For the Linux port, we kept this structure pretty much intact | ||
40 | * and use it internally (because the existing code groks it). | ||
