This thread serves to combine my notes, and Solidcore's, on this topic. 

Notes regarding filesystem objects.

The functions are prefixed with the name of the FS/fs module file. 

Some relevant structures for IRIX's VFS are in the below codeblocks. These were RE'd by Endeavour and myself later on:

Code:

typedef struct vfsops {

Code:

    bhv_position_t    vf_position;   

Code:

    int    (*vfs_mount)(struct vfs *, struct vnode *,

Code:

                 struct mounta *, char *, struct cred *);

Code:

                   

Code:

    int    (*vfs_rootinit)(struct vfs *);

Code:

                   

Code:

    int    (*vfs_mntupdate)(bhv_desc_t *, struct vnode *,

Code:

                 struct mounta *, struct cred *);

Code:

    int    (*vfs_dounmount)(bhv_desc_t *, int, struct vnode *,

Code:

                 struct cred *);

Code:

    int    (*vfs_unmount)(bhv_desc_t *, int, struct cred *);

Code:

    int    (*vfs_root)(bhv_desc_t *, struct vnode **);

Code:

    int    (*vfs_statvfs)(bhv_desc_t *, struct statvfs *, struct vnode *);

Code:

    int    (*vfs_sync)(bhv_desc_t *, int, struct cred *);

Code:

    int    (*vfs_vget)(bhv_desc_t *, struct vnode **, struct fid *);

Code:

    int    (*vfs_mountroot)(bhv_desc_t *, enum whymountroot);

Code:

    int    (*vfs_realvfsops)(vfs_t *, struct mounta *, struct vfsops **);

Code:

        int     (*vfs_import)(vfs_t *);

Code:

   

Code:

    int    (*vfs_quotactl)(bhv_desc_t *, int, int, caddr_t);

Code:

    int    (*vfs_force_pinned)(bhv_desc_t *);

Code:

    int     vfs_ops_magic;         

Code:

        __uint64_t   vfs_ops_version;   

Code:

        __uint64_t   vfs_ops_flags;   

Code:

} vfsops_t;

typedef struct vfssw {
    char        *vsw_name;     
    int        (*vsw_init)(struct vfssw *, int);
    vfsops_t    *vsw_vfsops;       
    struct vnodeops    *vsw_vnodeops;       
    void        *vsw_fill;       
    long        vsw_flag;       
} vfssw_t

This is what we were able to find out. 


This is a companion thread to a new bounty replacing an abortive one.
