In the Linux kernel, the following vulnerability has been resolved:
cifs: Fix connections leak when tlink setup failed
If the tlink setup failed, lost to put the connections, then
the module refcnt leak since the cifsd kthread not exit.
Also leak the fscache info, and for next mount with fsc, it will
print the follow errors:
CIFS: Cache volume key already in use (cifs,127.0.0.1:445,TEST)
Let's check the result of tlink setup, and do some cleanup.

CVE-2022-49822 [MEDIUM] kernel: cifs: Fix connections leak when tlink setup failed
kernel: cifs: Fix connections leak when tlink setup failed
In the Linux kernel, the following vulnerability has been resolved:
cifs: Fix connections leak when tlink setup failed
If the tlink setup failed, lost to put the connections, then
the module refcnt leak since the cifsd kthread not exit.
Also leak the fscache info, and for next mount with fsc, it will
print the follow errors:
CIFS: Cache volume key already in use (cifs,127.0.0.1:445,TEST)
Let's check the result of tlink setup, and do some cleanup.
Statement: A resource leak was identified in the CIFS filesystem module due to missing cleanup when tlink setup fails during mount. This causes leaked module references, persistent kernel threads, and leftover fscache entries that may block subsequent mounts.
