[PATCH 0/5] fscrypt: report correct st_size for encrypted symlinks

[Eric Biggers <ebiggers@kernel.org>]

This series makes the stat() family of syscalls start reporting the
correct size for encrypted symlinks.

See patch 1 for a detailed explanation of the problem and solution.

Patch 1 adds a helper function that computes the correct size for an
encrypted symlink.  Patches 2-4 make the filesystems with fscrypt
support use it, and patch 5 updates the documentation.

This series applies to mainline commit 3dbdb38e2869.

Eric Biggers (5):
  fscrypt: add fscrypt_symlink_getattr() for computing st_size
  ext4: report correct st_size for encrypted symlinks
  f2fs: report correct st_size for encrypted symlinks
  ubifs: report correct st_size for encrypted symlinks
  fscrypt: remove mention of symlink st_size quirk from documentation
