It is only true for HTX streams. The legacy code relies on ci_putblk() which is
already aware of the reserve. It is mandatory to not fill the reserve to let
other filters analysing data. It is especially true for the compression
filter. It needs at least 20 bytes of free space, plus at most 5 bytes per 32kB
block. So if the cache fully fills the channel's buffer, the compression will
not have enough space to do its job and it will block the data forwarding,
waiting for more free space. But if the buffer fully filled with input data (ie
no outgoing data), the stream will be frozen infinitely.
This patch must be backported to 1.9. It depends on the following patches:
* BUG/MEDIUM: cache/htx: Respect the reserve when cached objects are served
from the cache
* MINOR: channel/htx: Add HTX version for some helper functions
