[PATCH 05/16] hpfs: Convert hpfs_symlink_read_folio to use a folio

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

 



Remove the conversion back into a page and use the folio APIs throughout.
Remove the setting of PG_error instead of converting it; it is unused
by core code or by the rest of HPFS, so it serves no purpose here.
