This happens even without a VFS component using the block session. Just
adding part_blk gives the error.

I had to subtract the quotas for part_blk from the vfs quotas. That solved
the problem for me.

I changed the config to the following:
<start name="part_blk" caps="100">
<resource name="RAM" quantum="50M"/>
<provides><service name="Block"/></provides>
<config use_gpt="no">
<policy label_prefix="vfs" writeable="yes" partition="1"/>
<policy label_prefix="blk_crypt" writeable="yes" partition="6"/>
</config>
<route>
<service name="Block">
<child name="drivers" label="part_blk -> default"/>
</service>
<any-service> <parent/> </any-service>
</route>
</start>
However, it still gives the exact same errors. Strangely, init still
gives the warning:
[init] Warning: part_blk: could not revert session RAM quota
(service=Block cid=6 args='tx_buf_size=4194304, cap_quota=5,
label="part_blk -> ", ram_quota=4207830, diag=0' state=SERVICE_DENIED
ram_quota=4207830, cap_quota=5)
It looks like the label is not rewritten at all. changing "<service
name="Block">" into "<service name="Block" label=""> does not do
anything and the label inside the warning stays "part_blk -> ". Does
this give you any clue?
Also, placing part_blk on another init which is not the runtime init
also gives me these errors, even though the label is changed to "init ->
part_blk -> ".
