Subject: ceph: cleanup aborted requests when re-sending requests.
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=eb1b8af33c2e42a9a57fc0a7588f4a7b255d2e79;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

ceph: cleanup aborted requests when re-sending requests.

Aborted requests usually get cleared when the reply is received.
If MDS crashes, no reply will be received. So we need to cleanup
aborted requests when re-sending requests.
