[PATCH 00/36] ceph+fscrypt: context, filename, symlink and size handling support

I've not posted this in a while, so I figured it was a good time to do
so. This patchset is a pile of the mostly settled parts of the fscrypt
integration series. With this, pretty much everything but the actual
content encryption in files now works.

This series is also in the wip-fscrypt-size branch of the ceph-client
tree:

https://github.com/ceph/ceph-client/tree/wip-fscrypt-size

It would also be nice to have an ack from Al Viro on patch #1, and from
Eric Biggers on #2-5. Those touch code outside of the ceph parts. If
they aren't acceptable for some reason, I'll need to find other ways to
handle them.

Jeff Layton (31):
vfs: export new_inode_pseudo
fscrypt: export fscrypt_base64url_encode and fscrypt_base64url_decode
fscrypt: export fscrypt_fname_encrypt and fscrypt_fname_encrypted_size
fscrypt: add fscrypt_context_for_new_inode
fscrypt: uninline and export fscrypt_require_key
ceph: preallocate inode for ops that may create one
ceph: crypto context handling for ceph
ceph: parse new fscrypt_auth and fscrypt_file fields in inode traces
ceph: add fscrypt_* handling to caps.c
ceph: add ability to set fscrypt_auth via setattr
ceph: implement -o test_dummy_encryption mount option
ceph: decode alternate_name in lease info
ceph: add fscrypt ioctls
ceph: make ceph_msdc_build_path use ref-walk
ceph: add encrypted fname handling to ceph_mdsc_build_path
ceph: send altname in MClientRequest
ceph: encode encrypted name in dentry release
