btrfs: refactor how we iterate ordered extent in
btrfs_invalidatepage()
btrfs: introduce helpers for subpage dirty status
btrfs: introduce helpers for subpage writeback status
btrfs: allow btree_set_page_dirty() to do more sanity check on
subpage
metadata
btrfs: support subpage metadata csum calculation at write time
btrfs: make alloc_extent_buffer() check subpage dirty bitmap
btrfs: make the page uptodate assert to be subpage compatible
btrfs: make set/clear_extent_buffer_dirty() to be subpage compatible
btrfs: make set_btree_ioerr() accept extent buffer and to be subpage
compatible
btrfs: add subpage overview comments
Moved from topic branch to misc-next.
Note sure if it's too late, but I inserted the last comment patch into
the wrong location.
In fact, there are 4 more patches to make
subpage metadata RW really work:
I took some time to go through these patches, which are lined up for
integration.
With this set of patches that are being integrated, we don't yet
support RW mount of filesystem if PAGESIZE > sectorsize as a whole.
Subpage metadata RW support, how is it to be used in the production?
OR How is this supposed to be tested?
OR should you just cleanup the title as preparatory patches to support
subpage RW? It is confusing.
Thanks, Anand
btrfs: make lock_extent_buffer_for_io() to be subpage compatible
btrfs: introduce submit_eb_subpage() to submit a subpage metadata page
btrfs: introduce end_bio_subpage_eb_writepage() function
btrfs: introduce write_one_subpage_eb() function
Those 4 patches should be before the final comment patch.
Should I just send the 4 patches in a separate series?
Sorry for the bad split, it looks like multi-series patches indeed has
such problem...
Thanks,
Qu
