 Modified Files:
 	src/sys/fs/tmpfs: tmpfs_vfsops.c
 
 Log Message:
 In the event that loading the root vnode fails, bail out of
 tmpfs_mount instead of crashing.
 
 Came up in PR 51436, where kmem issues caused internal allocations to
 wrongly fail. However, that could happen for real sometime (e.g.
 probably if you tried to mount a new tmpfs when the system was very
 low on memory, or possibly for other reasons entirely) and crashing
 isn't the ticket.
 
 (This is not a fix for PR 51436)
