Subject: f2fs: Pass a folio to __f2fs_find_entry()
X-Git-Tag: v6.16-rc1~115^2~57
X-Git-Url: https://git.kernel.dk/?a=commitdiff_plain;h=c190a13d71e7d9c3ccad1d17e00285888857b974;p=linux-block.git

f2fs: Pass a folio to __f2fs_find_entry()

Also pass a folio to f2fs_find_in_inline_dir() and find_in_level().
Remove three calls to compound_head().
