bcache: Convert to DEFINE_SHOW_ATTRIBUTE

2020-10-02T20:25:29Z

Use DEFINE_SHOW_ATTRIBUTE macro to simplify the code. As inode->iprivate equals to third parameter of debugfs_create_file() which is NULL. So it's equivalent to original code logic. Signed-off-by: Qinglang Miao Signed-off-by: Coly Li Signed-off-by: Jens Axboe

closures: fix a race on wakeup from closure_sync

2019-09-03T14:08:31Z

The race was when a thread using closure_sync() notices cl->s->done == 1 before the thread calling closure_put() calls wake_up_process(). Then, it's possible for that thread to return and exit just before wake_up_process() is called - so we're trying to wake up a process that no longer exists. rcu_read_lock() is sufficient to protect against this, as there's an rcu barrier somewhere in the process teardown path.

bcache: do not check return value of debugfs_create_dir()

2018-08-09T14:21:01Z

Greg KH suggests that normal code should not care about debugfs. Therefore no matter successful or failed of debugfs_create_dir() execution, it is unncessary to check its return value. There are two functions called debugfs_create_dir() and check the return value, which are bch_debug_init() and closure_debug_init(). This patch changes these two functions from int to void type, and ignore return values of debugfs_create_dir(). This patch does not fix exact bug, just makes things work as they should.

bcache: move closure debug file into debug directory

2018-03-19T02:15:20Z

In current code closure debug file is outside of debug directory and when unloading module there is lack of removing operation for closure debug file, so it will cause creating error when trying to reload module. This patch move closure debug file into "bcache" debug direcory so that the file can get deleted properly.
