f76c449ec0 bcachefs-tools: fix endian problems between bit spinlocks and futexes 
bcachefs format on a big-endian (s390x) machine crashes down in the
rhashtable code imported from the kernel. The reason this occurs
lies within the rht_lock() -> bit_spin_lock() code, the latter of
which casts bitmaps down to 32-bits to satisfy the requirements of
the futex interface.

The specific problem here is that a 64 -> 32 bit cast doesn't refer
to the lower 8 bytes on a big endian machine, which means setting
bit number 0 in the 32-bit map actually corresponds to bit 32 in the
64-bit map. The rhashtable code specifically uses bit zero of the
bucket pointer for exclusion and uses native bitops elsewhere (i.e.
__rht_ptr()) to identify NULL pointers. If bit 32 of the pointer is
set by the locking code instead of bit 0, an otherwise NULL pointer
looks like a non-NULL value and results in a segfault.

The bit spinlock code imported by the kernel is originally intended
to work with unsigned long. The kernel code is able to throttle the
cpu directly when under lock contention, while the userspace
implementation relies on the futex primitives to emulate reliable
blocking. Since the futex interface introduces the 32-bit
requirement, isolate the associated userspace hack to that
particular code.

Restore the native bitmap behavior of the bit spinlock code to
address the rhashtable problem described above. Since this is not
compatible with the futex interface, create a futex wrapper
specifically to convert the native bitmap type to a 32-bit virtual
address and mask value for the purposes of waiting/waking when under
lock contention.

4f6b28f54f A small compile fix 
Hi

Here I'm sending a small compile fix for bcachefs-tools.

Without this patch, I get this error:

The futex() function is declared in

It is not declared in linux/futex.h, so we need to include urcu/futex.h

81aef33957 Don't run shrinkers without GFP_KERNEL 
This would correspond to GFP_RECLAIM in the kernel - but we don't
distinguish between different types of reclaim here.

This solves a deadlock in the btree node memory allocation path - we
allocate with the btree node cache lock held but without GFP_KERNEL set.
