Or Har-Toov 3f5f6321f1 IB/core: Annotate umem_mutex acquisition under fs_reclaim for lockdep ... Following the fix in the previous commit ("IB/mlx5: Fix potential deadlock in MR deregistration"), teach lockdep explicitly about the locking order between fs_reclaim and umem_mutex. The previous commit resolved a potential deadlock scenario where kzalloc(GFP_KERNEL) was called while holding umem_mutex, which could lead to reclaim and eventually invoke the MMU notifier (mlx5_ib_invalidate_range()), causing a recursive acquisition of umem_mutex. To prevent such issues from reoccurring unnoticed in future code changes, add a lockdep annotation in ib_init_umem_odp() that simulates taking umem_mutex inside a reclaim context. This makes lockdep aware of this locking dependency and ensures that future violations—such as calling kzalloc() or any memory allocator that may enter reclaim while holding umem_mutex—will immediately raise a lockdep warning.
