f2fs: should not truncate blocks during roll-forward recovery

2022-04-22T01:57:09+00:00

If the file preallocated blocks and fsync'ed, we should not truncate them during
roll-forward recovery which will recover i_size correctly back.

f2fs: keep io_flags to avoid IO split due to different op_flags in two fio holders

2022-04-20T18:16:43+00:00

Let's attach io_flags to bio only, so that we can merge IOs given original
io_flags only.

f2fs: Get the superblock from the mapping instead of the page

2022-04-01T18:40:44+00:00

It's slightly more efficient to go directly from the mapping to the
superblock than to go from the page.  Now that these routines have
the mapping passed to them, there's no reason not to use it.

f2fs: Correct f2fs_dirty_data_folio() conversion

2022-04-01T18:40:44+00:00

I got the return value wrong.  Very little checks the return value
from set_page_dirty(), so nobody noticed during testing.

fs: Pass an iocb to generic_perform_write()

2022-04-01T18:40:44+00:00

We can extract both the file pointer and the pos from the iocb.
This simplifies each caller as well as allowing generic_perform_write()
to see more of the iocb contents in the future.

Pull NVMe write streams removal from Jens Axboe:
 "This removes the write streams support in NVMe. No vendor ever really
  shipped working support for this, and they are not interested in
  supporting it.

  With the NVMe support gone, we have nothing in the tree that supports
  this. Remove passing around of the hints.

  The only discussion point in this patchset imho is the fact that the
  file specific write hint setting/getting fcntl helpers will now return
  -1/EINVAL like they did before we supported write hints. No known
  applications use these functions, I only know of one prototype that I
  help do for RocksDB, and that's not used. That said, with a change
  like this, it's always a bit controversial. Alternatively, we could
  just make them return 0 and pretend it worked. It's placement based
  hints after all"

Merge tag 'folio-5.18b' of git://git.infradead.org/users/willy/pagecache

2022-03-23T01:26:56+00:00

Pull filesystem folio updates from Matthew Wilcox:
 "Primarily this series converts some of the address_space operations to
  take a folio instead of a page.

  Notably:

   - a_ops->is_partially_uptodate() takes a folio instead of a page and
     changes the type of the 'from' and 'count' arguments to make it
     obvious they're bytes.

   - a_ops->invalidatepage() becomes ->invalidate_folio() and has a
     similar type change.

   - a_ops->launder_page() becomes ->launder_folio()

   - a_ops->set_page_dirty() becomes ->dirty_folio() and adds the
     address_space as an argument.

  There are a couple of other misc changes up front that weren't worth
  separating into their own pull request"
