xfs: use %px for data pointers when debugging
Starting with commit 57e734423ad ("vsprintf: refactor %pK code out of pointer"), the behavior of the raw '%p' printk format specifier was changed to print a 32-bit hash of the pointer value to avoid leaking kernel pointers into dmesg. For most situations that's good. This is /undesirable/ behavior when we're trying to debug XFS, however, so define a PTR_FMT that prints the actual pointer when we're in debug mode. Note that %p for tracepoints still prints the raw pointer, so in the long run we could consider rewriting some of these messages as tracepoints. Signed-off-by: Darrick J.
