Still not a fan of that vs adding a proper helper.

Okay so I think lets instead annotate nvme_init_subsystem() with
__context_unsafe.

nvme_ns_head is allocated with kzalloc(), so explicitly initializing
nvme_ns_head::delayed_removal_secs to 0 in nvme_mpath_alloc_disk() is
redundant. Remove the redundant initialization, which also avoids a
false positive from Clang's context analysis.

Please split that into a prep patch.

Sure, I'll split that into a separate preparatory patch in the next
revision.

Thanks,
