The re-entrancy happens because the irq state is the OR of
the interrupt state and the resamplefd state. That is, we don't
want to show the state as 0 until we've had a chance to set the
resamplefd. But if the interrupt has _not_ gone low then
ioapic_set_irq is invoked again, causing an infinite loop.
This can only happen for a level-triggered interrupt, otherwise
irqfd_inject would immediately set the KVM_USERSPACE_IRQ_SOURCE_ID high
and then low. Fortunately, in the case of level-triggered interrupts the VMEXIT already happens because
TMR is set. Thus, fix the bug by restricting the lazy invocation
of the ack notifier to edge-triggered interrupts, the only ones that
need it.

The AMD SPI driver calls spi_master_put() in its ->remove() hook even

to spi_master_put().
This only leaves the call to spi_unregister_master() in the ->remove()

of spi_register_master() and drop the ->remove() hook altogether.

The functionality in xfs_diflags_to_linux() and xfs_diflags_to_iflags() are
nearly identical. The only difference is that *_to_linux() is called after
inode setup and disallows changing the DAX flag.
Combining them can be done with a flag which indicates if this is the initial
setup to allow the DAX flag to be properly set only at init time.
So remove xfs_diflags_to_linux() and call the modified xfs_diflags_to_iflags()
directly.
While we are here simplify xfs_diflags_to_iflags() to take struct xfs_inode and
use xfs_ip2xflags() to ensure future diflags are included correctly.

I ran into a linker warning in XFS that originates from a mismatch
between libelf, binutils and objtool when certain files in the kernel
are built with "gcc -g":
x86_64-linux-ld: fs/xfs/xfs_trace.o: unable to initialize decompress status for section .debug_info
After some discussion, nobody could identify why xfs sets this flag
here. CONFIG_XFS_DEBUG used to enable lots of unrelated settings, but
now its main purpose is to enable extra consistency checks and assertions
that are unrelated to the debug info.
Remove the Makefile logic to set the flag here. If anyone relies
on the debug info, this can simply be enabled again with the global
CONFIG_DEBUG_INFO option.
Dave Chinner writes:
I'm pretty sure it was needed for the original kgdb integration back
in the early 2000s. That was when SGI used to patch their XFS dev
tree with kgdb and debug symbols were needed by the custom kgdb
modules that were ported across from the Irix kernel debugger.
ISTR that the early kcrash kernel dump analysis tools (again,
originated from the Irix "icrash" kernel dump tools) had custom XFS
debug scripts that needed also the debug info to work correctly...
Which is a long way of saying "we don't need it anymore" instead of
"nobody knows why it was set"... :)
