[PATCH 0/9] THP iomap patches for 5.10

From: Matthew Wilcox (Oracle)
Date: Mon Aug 24 2020 - 11:19:42 EST


These patches are carefully plucked from the THP series. I would like
them to hit 5.10 to make the THP patchset merge easier. Some of these
are just generic improvements that make sense on their own terms, but
the overall intent is to support THPs in iomap.

I'll send another patch series later today which are the changes to
iomap which don't pay their own way until we actually have THPs in the
page cache. I would like those to be reviewed with an eye to merging
them into 5.11.

Matthew Wilcox (Oracle) (9):
iomap: Fix misplaced page flushing
fs: Introduce i_blocks_per_page
iomap: Use kzalloc to allocate iomap_page
iomap: Use bitmap ops to set uptodate bits
iomap: Support arbitrarily many blocks per page
iomap: Convert read_count to byte count
iomap: Convert write_count to byte count
iomap: Convert iomap_write_end types
iomap: Change calling convention for zeroing
