However, overlayfs was not adapted to handle this change. In ovl_cache_entry_new(), the code checks if d_type == DT_CHR to determine if an entry might be a whiteout. When fuse is used as the lower layer and sets high bits in d_type, this comparison fails, causing whiteout files to not be recognized properly and resulting in incorrect overlayfs behavior. Fix this by requiring callers of iterate_dir() to opt-in for getting flag bits in d_type outside of S_DT_MASK.

The same goes for simple_offset_rename_exchange(). Moreover, shmem_whiteout() expects that if it succeeds, the caller will progress to d_move(), i.e. that shmem_rename2() won't fail past the successful call of shmem_whiteout(). Not hard to fix, fortunately - mtree_store() can't fail if the index we are trying to store into is already present in the tree as a singleton. For simple_offset_rename_exchange() that's enough - we just need to be careful about the order of operations. For simple_offset_rename() solution is to preinsert the target into the tree for new_dir; the rest can be done without any potentially failing operations. That preinsertion has to be done in shmem_rename2() rather than in simple_offset_rename() itself - otherwise we'd need to deal with the possibility of failure after successful shmem_whiteout().

A reference is grabbed and not released, but it's not actually _stored_ anywhere. That works, but it's hard to follow and verify; among other things, we have no way to tell _which_ of the increments is intended to be an unpaired one. Worse, on removal we need to decide whether the reference had already been dropped, which can be non-trivial if that removal is on umount and we need to figure out if this dentry is pinned due to e.g. unlink() not done. Usually that is handled by using kill_litter_super() as ->kill_sb(), but there are open-coded special cases of the same (consider e.g. /proc/self). Things get simpler if we introduce a new dentry flag (DCACHE_PERSISTENT) marking those "leaked" dentries. Having it set claims responsibility for +1 in refcount. The end result this series is aiming for: - get these unbalanced dget() and dput() replaced with new primitives that would, in addition to adjusting refcount, set and clear persistency flag. - instead of having kill_litter_super() mess with removing the remaining "leaked" references (e.g. for all tmpfs files that hadn't been removed prior to umount), have the regular shrink_dcache_for_umount() strip DCACHE_PERSISTENT of all dentries, dropping the corresponding reference if it had been set. After that kill_litter_super() becomes an equivalent of kill_anon_super(). Doing that in a single step is not feasible - it would affect too many places in too many filesystems. It has to be split into a series. This work has really started early in 2024; quite a few preliminary pieces have already gone into mainline.

Add support for simple, recallable-only directory delegations. This was decided at the fall NFS Bakeathon where the NFS client and server maintainers discussed how to merge directory delegation support. The approach starts with recallable-only delegations for several reasons: 1. RFC8881 has gaps that are being addressed in RFC8881bis. In particular, it requires directory position information for CB_NOTIFY callbacks, which is difficult to implement properly under Linux. The spec is being extended to allow that information to be omitted. 2. Client-side support for CB_NOTIFY still lags. The client side involves heuristics about when to request a delegation. 3. Early indication shows simple, recallable-only delegations can help performance. Anna Schumaker mentioned seeing a multi-minute speedup in xfstests runs with them enabled. With these changes, userspace can also request a read lease on a directory that will be recalled on conflicting accesses. This may be useful for applications like Samba. Users can disable leases altogether via the fs.leases-enable sysctl if needed.
