exportfs: use dget_parent

2010-10-26T01:26:13+00:00

Use dget_parent instead of opencoding it.  This simplifies the code, but
more importanly prepares for the more complicated locking for a parent
dget in the dcache scale patch series.

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

EXPORTFS: handle NULL returns from fh_to_dentry()/fh_to_parent()

2008-12-09T03:49:32+00:00

While 440037287c5 "[PATCH] switch all filesystems over to
d_obtain_alias" removed some cases where fh_to_dentry() and
fh_to_parent() could return NULL, there are still a few NULL returns
left in individual filesystems.  Thus it was a mistake for that commit
to remove the handling of NULL returns in the callers.

Revert those parts of 440037287c5 which removed the NULL handling.

(We could, alternatively, modify all implementations to return -ESTALE
instead of NULL, but that proves to require fixing a number of
filesystems, and in some cases it's arguably more natural to return
NULL.)

Thanks to David for original patch and Linus, Christoph, and Hugh for
review.

CRED: Pass credentials through dentry_open()

2008-11-13T23:39:22+00:00

Pass credentials through dentry_open() so that the COW creds patch can have
SELinux's flush_unauthorized_files() pass the appropriate creds back to itself
when it opens its null chardev.

The security_dentry_open() call also now takes a creds pointer, as does the
dentry_open hook in struct security_operations.

[PATCH] prepare vfs_readdir() callers to returning filldir result

2008-10-23T09:13:10+00:00

It's not the final state, but it allows moving ->readdir() instances
to passing filldir return value to caller of vfs_readdir().

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].
