Subject: filesystem: Details of mount_ref_count in struct mount
Date: Wed, 20 Apr 2016 21:54:13 +0900 [thread overview]
Message-ID: <CAB6A5-AZDJ-g6k_T0X6f+7wcAQcNi-KJLHV5nGkR2WcFL4UnMQ@mail.gmail.com> (raw)
Hi,
I am looking into an issue where unmounting /data is failing.
I receive -EBUSY as the sum off all mnt_count(mnt->mnt_pcp->mnt_count) of
all cpu's > 2 (the value in my case is 3).
I am debugging from linux crash dump.
Is there any way that I can know the owners/responsible drivers that have
incereased this refcount and left it like that without decrementing?
Kindly share any helpful information. Thank you.
Best Regards,
Manty
