Re: [PATCH] net: qrtr: ns: Raise lookup limit to 128

[Łukasz Patron]

Hi,

After merging v6.6.142 into a downstream AOSP device, it's stuck on
boot animation and following log spam can be observed in dmesg:

E qrtr    : ctrl_cmd_new_lookup(): QRTR client node exceeds max lookup limit!
E qrtr    : qrtr_ns_worker(): failed while handling packet from 1:16600

No idea why it needs more than 64 client lookups, but it appears to
work fine with 128 as it did when there were no limits.

Also, I don't really have a good way to investigate what it needs all
these lookups for as most of the userspace is closed source. Perhaps
someone working at Qualcomm could have some ideas.
