r_safe_completion is currently, and has always been, signaled only if on-disk ack was requested. It's there for fsync and syncfs, which wait for in-flight writes to flush - all data write requests set ONDISK. However, the pool perm check code introduced in 4.2 sends a write request with only ACK set. An unfortunately timed syncfs can then hang forever: r_safe_completion won't be signaled because only an unsafe reply was requested. We could patch ceph_osdc_sync() to skip !ONDISK write requests, but that is somewhat incomplete and yet another special case. Instead, rename this completion to r_done_completion and always signal it when the OSD client is done with the request, whether unsafe, safe, or error. This is a bit cleaner and helps with the cancellation code. Reported-by: Yan, Zheng <zyan@redhat.com> Signed-off-by: Ilya Dryomov <idryomov@gmail.com> |
