Subject[PATCH 0/3] btrfs: Convert kmap/memset/kunmap to memzero_user()
Date
From: Ira Weiny <ira.weiny@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.

Thanks,
Ira

Ira Weiny (3):
iov_iter: Lift memzero_page() to highmem.h
mm/highmem: Convert memzero_page() to kmap_local_page()
btrfs: Use memzero_page() instead of open coded kmap pattern
