Subject: [PATCH -V20 00/12] Generic name to handle and open by handle syscalls
Date: Wed, 29 Sep 2010 01:06:38 +0530 [thread overview]
Message-ID: <1285702610-32733-1-git-send-email-aneesh.kumar@linux.vnet.ibm.com> (raw)
Hi,
The below set of patches implement open by handle support using exportfs
operations. This allows user space application to map a file name to file
handle and later open the file using handle. This should be usable
for userspace NFS [1] and 9P server [2]. XFS already support this with the ioctls
XFS_IOC_PATH_TO_HANDLE and XFS_IOC_OPEN_BY_HANDLE.

[2] http://thread.gmane.org/gmane.comp.emulators.qemu/68992
git repo for the patchset at:
git://git.kernel.org/pub/scm/linux/kernel/git/kvaneesh/linux-open-handle.git open-by-handle
Test case can be found at
http://git.kernel.org/?p=fs/ext2/kvaneesh/handle-test.git
git://git.kernel.org/pub/scm/fs/ext2/kvaneesh/handle-test.git
Changes from V19:
a) Drop handle based chown, xattr, utimes syscalls
b) Rebased to latest linus kernel (050026feae5bd4fe2db4096b63b15abce7c47faa)
