NFS: Fix races nfs_page_group_destroy() vs nfs_destroy_unlinked_subrequests()
[ Upstream commit 08ca8b21f760c0ed5034a5c122092eec22ccf8f4 ]
When a subrequest is being detached from the subgroup, we want to
ensure that it is not holding the group lock, or in the process
of waiting for the group lock.
Fixes: 5b2b5187fa85 ("NFS: Fix nfs_page_group_destroy() and nfs_lock_and_join_requests() race cases")
