From: Ira Weiny <ira.we...@intel.com> Previously this was submitted to convert to zero_user()[1]. zero_user() is not the same as memzero_user() and in fact some zero_user() calls may be better off as memzero_user(). Regardless it was incorrect to convert btrfs to zero_user().
This series corrects this by lifting memzero_user(), converting it to kmap_local_page(), and then using it in btrfs.
