From 64dba1fbb43a778136e934d7997e92d19d60260d Mon Sep 17 00:00:00 2001 From: chao an Date: Wed, 18 Sep 2024 09:13:18 +0800 Subject: [PATCH] fs/reference_count: set default reference count option to n Most of developers will not have the scenarios of open/close file descriptors in multi-threads, The default option will incur additional code size overhead for such devices. this PR will preserve the behavior before PR#13296 was introduced, and ensure that the default code size is not affected. Note that this option will ensure the safety of access to the file system from multi-tasks (Task A blocking rw(fd), then Task B close(fd)), the disadvantage is that it will increase the amount of code-size, there is no need to enable this option if the application could ensure he file operations are safe.
