[PATCH] Wrong page aligned size calculation in ioremapping code
Hi, over the years since when I last reported this (and then lost track of it) this has been fixed in most places/architectures - but two instances still remain (or have appeared newly?), so here is the fix, and this time I'm gonna make sure it gets applied ;-) The patch is untested, but I guess it's simple en... 15 Jun 2010 14:17

[PATCH -V14 0/11] Generic name to handle and open by handle syscalls
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... 15 Jun 2010 14:17

[PATCH -V14 04/11] vfs: Allow handle based open on symlinks
The patch update may_open to allow handle based open on symlinks. The file handle based API use file descritor returned from open_by_handle_at to do different file system operations. To find the link target name we need to get a file descriptor on symlinks. Signed-off-by: Aneesh Kumar K.V <aneesh.kumar(a)linux.vnet... 15 Jun 2010 14:17

[PATCH -V14 05/11] vfs: Support null pathname in readlink
From: NeilBrown <neilb(a)suse.de> This enables to use readlink to get the link target name from a file descriptor point to the link. This can be used with open_by_handle syscall that returns a file descriptor for a link. We can then use this file descriptor to get the target name.
