[PATCH v2 16/16] Remove usage of buffer_local_flags |
Date: |
Sat, 21 Nov 2020 21:34:45 -0500 |
Previously, we used the buffer_local_flags structure to track which
fields in buffer_defaults contain usable defaults, as well as the
index into local_flags to use for each struct buffer field.
After the immediate previous commit, we don't need the index into
local_flags anymore. So all we need is to know whether the fields in
buffer_defaults contain usable defaults. We can do that by just
setting unusable and unused buffer_defaults fields to Qunbound. Then
we can delete buffer_local_flags.
In these changes, we delete buffer_local_flags and ensure that
buffer_defaults is initialized appropriately for this new usage.
