Message-ID: <20210202081010.GZ20820@kadam> (raw)

Commit 36211f7fc1e7 ("Bluetooth: Pause service discovery for suspend")
seems like a bugfix as well but there is no Fixes tag there either. The
commit message should be more clear what the effect of the bug looks
like to the user. I like to write something like this:
[PATCH] Bluetooth: Pause service discovery for suspend
Just like MGMT_OP_START_DISCOVERY, we should reject
MGMT_OP_START_SERVICE_DISCOVERY with MGMT_STATUS_BUSY when we are paused
for suspend. This bug was discovered by auditing the software and no
one has complained about it, but presumably it leads to a hanged process
because the cmd cannot complete.
Sometimes it's hard to know what the affect of a bug is, but since
you're working in the subsystem then you probably have a better guess
than the rest of us so even a guess is useful.
regards,
dan carpenter
