  • 5fe0c2378   exportfs: Return the minimum required handle size ... Browse Code »

    The exportfs encode handle function should return the minimum required
    handle size. This helps user to find out the handle size by passing 0
    handle size in the first step and then redoing to the call again with
    the returned handle size value.

  • 8e656fd51   nilfs2: make snapshots in checkpoint tree exportable ... Browse Code »

    The previous export operations cannot handle multiple versions of
    a filesystem if they belong to the same sb instance.

    This adds a new type of file handle and extends export operations so
    that they can get the inode specified by a checkpoint number as well
    as an inode number and a generation number.

  • f501912a3   commit_metadata export operation replacing nfsd_sync_dir ... Browse Code »

    - Add commit_metadata export_operation to allow the underlying filesystem to
    decide how to commit an inode most efficiently.

    - Usage of nfsd_sync_dir and write_inode_now has been replaced with the
    commit_metadata function that takes a svc_fh.

    - The commit_metadata function calls the commit_metadata export_op if it's
    there, or else falls back to sync_inode instead of fsync and write_inode_now
    because only metadata need be synced here.

    - nfsd4_sync_rec_dir now uses vfs_fsync so that commit_metadata can be static

    The raw field's size can vary so we use a zero sized array since
    gcc will not allow a variable sized array inside a union. This
    has been tested with ext3 and gfs2 and relates to the bug

  • e38f98175   exportfs: update documentation ... Browse Code »

    Update documentation to the current state of affairs. Remove duplicated
    method descruptions in exportfs.h and point to Documentation/filesystems/
    Exporting instead. Add a little file header comment in expfs.c describing
    what's going on and mentioning Neils and my copyright [1].

  • 2596110a3   exportfs: add new methods ... Browse Code »

    Add the guts for the new filesystem API to exportfs.

    There's now a fh_to_dentry method that returns a dentry for the object looked
    for given a filehandle fragment, and a fh_to_parent operation that returns the
    dentry for the encoded parent directory in case the file handle contains it.

    There are default implementations for these methods that only take a callback
    for an nfs-enhanced iget variant and implement the rest of the semantics.

  • 6e91ea2bb   exportfs: add fid type ... Browse Code »

    This patchset is a medium scale rewrite of the export operations interface.
    The goal is to make the interface less complex, and easier to understand from
    the filesystem side, aswell as preparing generic support for exporting of
    64bit inode numbers.

    This touches all nfs exporting filesystems, and I've done testing on all of
    the filesystems I have here locally (xfs, ext2, ext3, reiserfs, jfs)

    This patch:

    Add a structured fid type so that we don't have to pass an array of u32 values
    around everywhere. It's a union of possible layouts.

    As a start there's only the u32 array and the traditional 32bit inode format,
    but there will be more in one of my next patchset when I start to document the
    various filehandle formats we have in lowlevel filesystems better.

    Also add an enum that gives the various filehandle types human- readable
    names.

    Note: Some people might think the struct containing an anonymous union is
    ugly, but I didn't want to pass around a raw union type.

  • d37065cd6   knfsd: exportfs: add procedural interface for NFSD ... Browse Code »

    Currently NFSD calls directly into filesystems through the export_operations
    structure. I plan to change this interface in various ways in later patches,
    and want to avoid the export of the default operations to NFSD, so this patch
    adds two simple exportfs_encode_fh/exportfs_decode_fh helpers for NFSD to call
    instead of poking into exportfs guts.

    currently the export_operation structure and helpers related to it are in
    fs.h. fs.h is already far too large and there are very few places needing the
    export bits, so split them off into a separate header.
