[00/20] Convert aops->migratepage to aops->migrate_folio

Message

Matthew Wilcox June 6, 2022, 8:40 p.m. UTC

I plan to submit these patches through my pagecache tree in the upcoming
merge window.  I'm pretty happy that most filesystems are now using
common code for ->migrate_folio; it's not something that most filesystem
people want to care about.  I'm running xfstests using xfs against it now,
but it's little more than compile tested for other filesystems.
