  ceph: assert loop invariants in ceph_writepages_start() (2026-02-11 19:14:32 +0100)

----------------------------------------------------------------
This adds support for the upcoming aes256k key type in CephX that is
based on Kerberos 5 and brings a bunch of assorted CephFS fixes from
Ethan and Sam.  One of Sam's patches in particular undoes a change in
the fscrypt area that had an inadvertent side effect of making CephFS
behave as if mounted with wsize=4096 and leading to the corresponding
degradation in performance, especially for sequential writes.

----------------------------------------------------------------
Ilya Dryomov (5):
      libceph: define and enforce CEPH_MAX_KEY_LEN
      libceph: generalize ceph_x_encrypt_offset() and ceph_x_encrypt_buflen()
      libceph: introduce ceph_crypto_key_prepare()
      libceph: add support for CEPH_CRYPTO_AES256KRB5
      libceph: adapt ceph_x_challenge_blob hashing and msgr1 message signing

Sam Edwards (4):
      ceph: do not propagate page array emplacement errors as batch errors
      ceph: fix write storm on fscrypted files
      ceph: remove error return from ceph_process_folio_batch()
      ceph: assert loop invariants in ceph_writepages_start()

ethanwu (2):
      ceph: supply snapshot context in ceph_zero_partial_object()
      ceph: supply snapshot context in ceph_uninline_data()
