Subject: staging/lustre/llite: A not locked mutex can be unlocked.
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=e06c9dfec0f3738409b3936dcd0a4ae126acac07;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

staging/lustre/llite: A not locked mutex can be unlocked.

In case of memory pressure a not locked mutex can be unlocked
in function ll_file_open(). This is not allowed and subsequent
behavior is not defined.
