[ Upstream commit 68762148d1 ]
rds_rm_zerocopy_callback() uses list_add_tail() with swapped
arguments. This links the list head with the new entry, losing
the references to the remaining part of the list.
Fixes: 9426bbc6de ("rds: use list structure to track information for zerocopy completion notification")
