more readable not having to deal with several buffers and possible race
conditions. (but just my view on the topic)
Thanks a lot for your answer. I

As rule of thumb I would say:
- use struct blob_buf b = {0}; in the function as local variable
- free after using it
- use "struct ubus_context *ctx_local" in callback functions to
differentiate between global ctx pointer and local callback variables
In the examples it is also freed. However,
Since I saw there were some new patches, e.g., procd, fixing
blob_buf_free() calls.
I asked several months ago: "Should you call blob_buf_free() after
calling blob_buf_init()?"
