Public bug reported:
The kernel is a rebuild of the Ubuntu source tree with a small number of
xen related patches. On a small percentage of boots we encounter a
repeated kernel warning which comes from fs/inode.c:
if (!inode->i_nlink) {
WARN_ON(atomic_long_read(&inode->i_sb->s_remove_count) == 0);
atomic_long_dec(&inode->i_sb->s_remove_count);
}
Using strace to attach to the pid logged in the warning the filesystem
is a tmpfs (either separate, e.g. /run or as the writeable layer of an
aufs overlay for /). This can be raised for different filesystem
operations, in this example do_unlinkat, others do_renameat2. The
problem does not seem to be hardware specific as we have encountered on
five different systems.
