First, instead of open-coding the vmalloc() fallback, use the new
kvzalloc() helper. Second, use memalloc_nofs_{save,restore}() instead of
GFP_NOFS, as vmalloc() uses some GFP_KERNEL allocations internally which
could lead to deadlocks.

telling the user soon enough that send/receive solely operates on
subvolume snapshots instead of the original (read/write) subvolumes.
So, change the first fe

due to warnings not to use raid56, not that I think this impacts my

One of the disks in the array started to go bad. Some bad sectors
meant one of my video files was unable to be read. This issue was
