Subject: [PATCH net v2 0/3] net: ipa: fix two replenish bugs
Date: Wed, 12 Jan 2022 07:30:09 -0600 [thread overview]
Message-ID: <20220112133012.778148-1-elder@linaro.org> (raw)
This series contains two fixes for bugs in the IPA receive buffer
replenishing code. The (new) second patch defines a bitmap to
represent endpoint the replenish enabled flag. Its purpose is to
prepare for the third patch, which adds an additional flag.
Version 2 of this series uses bitmap operations in the second bug
fix rather than an atomic variable, as suggested by Jakub.
