The patch titled
Subject: mm: fix kernel-doc markups
has been removed from the -mm tree. Its filename was
mm-fix-kernel-doc-markups.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
From: Mauro Carvalho Chehab <mchehab+huawei@xxxxxxxxxx>
Subject: mm: fix kernel-doc markups
Kernel-doc markups should use this format:
identifier - description
Fix some issues on mm files:
1) The definition for get_user_pages_locked() doesn't follow it. Also,
it expects a short descrpition at the header, followed by a long one,
after the parameters. Fix it.
2) Kernel-doc requires that a kernel-doc markup to be immediately below
the function prototype, as otherwise it will rename it. So, move
get_pfnblock_flags_mask() description to the right place.
3) Make invalidate_mapping_pagevec() to also follow the expected
kernel-doc format.
While here, fix a few minor English syntax issues, as suggested
by Matthew:
will used -> will be used
similar with -> similar to
