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