2026-01-05drm/amdkfd: Fix signal_eviction_fence() bool return valueSrinivasan Shanmugam
signal_eviction_fence() is declared to return bool, but returns -EINVAL when no eviction fence is present. This makes the "no fence" or "the NULL-fence" path evaluate to true and triggers a Smatch warning. v2: Return true instead to explicitly indicate that there is no eviction fence to signal and that eviction is already complete. This matches the existing caller logic where a NULL fence means "nothing to do" and allows restore handling to proceed normally.

2026-01-05libceph: reset sparse-read state in osd_fault()Sam Edwards
When a fault occurs, the connection is abandoned, reestablished, and any pending operations are retried. The OSD client tracks the progress of a sparse-read reply using a separate state machine, largely independent of the messenger's state. If a connection is lost mid-payload or the sparse-read state machine returns an error, the sparse-read state is not reset. The OSD client will then interpret the beginning of a new reply as the continuation of the old one. If this makes the sparse-read machinery enter a failure state, it may never recover, producing loops like: libceph: [0] got 0 extents libceph: data len 142248331 != extent len 0 libceph: osd0 (1)...:6801 socket error on read libceph: data len 142248331 != extent len 0 libceph: osd0 (1)...:6801 socket error on read Therefore, reset the sparse-read state in osd_fault(), ensuring retries start from a clean state.

2026-01-05libceph: return the handler error from mon_handle_auth_done()Ilya Dryomov
Currently any error from ceph_auth_handle_reply_done() is propagated via finish_auth() but isn't returned from mon_handle_auth_done(). This results in higher layers learning that (despite the monitor considering us to be successfully authenticated) something went wrong in the authentication phase and reacting accordingly, but msgr2 still trying to proceed with establishing the session in the background. In the case of secure mode this can trigger a WARN in setup_crypto() and later lead to a NULL pointer dereference inside of prepare_auth_signature().
