Subject: Btrfs: async-thread: fix possible memory leak
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=3bf10418675cb424724b5cb9d7725b234defe1fd;p=linux-beck.git

Btrfs: async-thread: fix possible memory leak

When kthread_run() returns failure, this worker hasn't been
added to the list, so btrfs_stop_workers() won't free it.
