These patches are on top of the torvalds tree.
F2FS currently supports casefolding and encryption, but not at
the same time. These patches aim to rectify that. In a later follow up,
this will be added for Ext4 as well. I've included one ext4 patch from
the previous set since it isn't in the f2fs b
This shifts the responsibility of setting up dentry operations from
fscrypt to the individual filesystems, allowing them to have their own
operations while still setting fscrypt's d_revalidate as appropriate.
Most filesystems can just use generic_set_encrypted_ci_d_ops, unless
they have their own
Expand f2fs's casefolding support to include encrypted directories. To
index casefolded+encrypted directories, we use the SipHash of the
casefolded name, keyed by a key derived from the directory's fscrypt
master key. This ensures that the dirhash doesn't leak information
about the plaintext file
This adds a function to set dentry operations at lookup time that will
work for both encrypted filenames and casefolded filenames.
A filesystem that supports both features simultaneously can use this
function during lookup preparations to set up its dentry operations once
fscrypt no longer does th
This patchset doesn't have a cover letter, and it doesn't apply to f2fs/dev, so
I'm not sure what its purpose is.

Added two ioctl to decompress/compress explicitly the compression
enabled file in disable_auto_compr mount option.
Using these two ioctls, the users can make a control of compression
and decompression of their files.

We will add a new disable_auto_compr mount option to turn off the
automaic compression on the compression enabled file, in order to
give discretion of choosing the target file and the timing of
compression to the user.

The stated reasons for separating fscrypt_master_key::mk_secret_sem from
the standard semaphore contained in every 'struct key' no longer apply.
First, due to commit a992b20cd4ee ("fscrypt: add
fscrypt_prepare_new_inode() and fscrypt_set_context()"),
