[PATCH 29/37] ocfs2: Convert ocfs2 to read_folio

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

 



This is a "weak" conversion which converts straight back to using pages.
A full conversion should be performed at some point, hopefully by
someone familiar with the filesystem.
