nilfs2: make snapshots in checkpoint tree exportable

2010-10-23T00:24:34+00:00

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.

commit_metadata export operation replacing nfsd_sync_dir

2010-02-20T21:13:44+00:00

- 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

nfs: new subdir Documentation/filesystems/nfs

We're adding enough nfs documentation that it may as well have its own
subdirectory.

Purely cosmetic for now, but we might as well get it merged ASAP.

Use a zero sized array for raw field in struct fid

2008-04-23T20:13:42+00:00

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

struct export_operations: adjust comments to match current members

2008-03-14T16:49:57+00:00

The comments in the definition of struct export_operations don't match the
current members.

Add a comment for the 2 new functions and remove 2 comments for unused ones.

exportfs: update documentation

2007-10-22T15:13:21+00:00

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].

exportfs: add new methods

2007-10-22T15:13:19+00:00

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.
