After some mv operations in filtetring area, we can not unregister filter module with msg of "Device or resource busy".

OS:

CentOS 6 or 7

Test:

rfsctl -f mvflt -i /test1
mv /test1/file1 /test1/file2
rfsctl -f mvflt -c
echo -n "1" > /sys/fs/redirfs/filters/mvflt/unregister
bash: echo: write error: Device or resource busy

Cause:

counter mismatch error at following line on "redirfs_unregister_filter" function:
-- if (atomic_read(&rflt->count) != 3) {

Would you please give me some solution?

Thanks.
