[PATCH v3 01/12] f2fs: drop usage of page_index

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]


From: Kairui Song <kasong@xxxxxxxxxxx>

page_index is needed for mixed usage of page cache and swap cache,
for pure page cache usage, the caller can just use page->index instead.

It can't be a swap cache page here, so just drop it.

[ This commit will not be needed once f2fs converted
  f2fs_mpage_readpages() to use folio]
