sys/uvm : uvm_amap.c
Log message:
sys/uvm: unwind failed amap copies
A PR_NOWAIT chunk allocation in amap_copy() may fail after earlier
chunks already contain copied anons; amap_free() requires an empty amap,
so direct cleanup trips its diagnostic assertion or leaves copied anon
references orphaned which may end who knows how.
Uuse amap_wipeout() instead to reverse the partial copy, release the
shared lock, and free the temporary amap.
