Comment 4 for bug 1873074

Workaround:
---

Clean the inode cache, which should remove the inode from
memory, and when it's needed again, it's initialized with
i_readcount zero.

$ echo 2 | sudo tee /proc/sys/vm/drop_caches

This may happen indirectly from time to time on systems,
as part of normal memory cleansing/reclaiming, and thus
the problem might be avoided or never noticed.

This might impact performance, as the inode and dentry
caches are flushed.
