Subject: page migration: fix wrong comment in address_space_operations.migratepage()
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=ef277c73ca3b1aade278036ae11640090681d558;p=linux.git

page migration: fix wrong comment in address_space_operations.migratepage()

There is no parameter "sync" in address_space_operations->migratepage().
It should be migrate_mode.  And the comment is for MIGRATE_ASYNC.
