Subject: Question about acpi_remove_address_space_handler() behavior if handler is running
Date: Sat, 4 Sep 2021 18:42:10 +0200 [thread overview]
Message-ID: <57a2a9fa-e296-85dc-75f8-94ccd0527204@gmail.com> (raw)
i801 i2c driver installs an own ACPI io handler. When discussing some driver
improvements one open question is about behavior of
acpi_remove_address_space_handler() if the handler is currently running.
Will the function wait until handler is finished? In other words, the actual
question is: Are we guaranteed that after the call to
acpi_remove_address_space_handler() the handler can't be running?
