[lustre-devel] [PATCH 02/22] Revert "staging: lustre: o2iblnd: Use list_for_each_entry_safe in kiblnd_destroy_fmr_pool_list"

[NeilBrown]

This reverts commit 0d33ec5f95fe068d7e96b6e7ed9216de93f6b5b0.

These loops really want to remove everything, and using a
  while(!list_empty())
loop makes this more obvious.
