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.
