iomap: add per-iomap_iter private data · 786f847f

由 Christoph Hellwig 提交于 5月 05, 2022

Allow the file system to keep state for all iterations.  For now only
wire it up for direct I/O as there is an immediate need for it there.

iomap: allow the file system to provide a bio_set for direct I/O · 908c5490

由 Christoph Hellwig 提交于 5月 05, 2022

Allow the file system to provide a specific bio_set for allocating
direct I/O bios.  This will allow file systems that use the
->submit_io hook to stash away additional information for file system
use.

To make use of this additional space for information in the completion
path, the file system needs to override the ->bi_end_io callback and
then call back into iomap, so export iomap_dio_bio_end_io for that.

btrfs: zoned: zone finish unused block group · 74e91b12

由 Naohiro Aota 提交于 5月 03, 2022

While the active zones within an active block group are reset, and their
active resource is released, the block group itself is kept in the active
block group list and marked as active. As a result, the list will contain
more than max_active_zones block groups. That itself is not fatal for the
device as the zones are properly reset.

However, that inflated list is, of course, strange. Also, a to-appear
patch series, which deactivates an active block group on demand, gets
confused with the wrong list.

So, fix the issue by finishing the unused block group once it gets
read-only, so that we can release the active resource in an early stage.

btrfs: zoned: properly finish block group on metadata write · 56fbb0a4

由 Naohiro Aota 提交于 5月 03, 2022

Commit be1a1d7a ("btrfs: zoned: finish fully written block group")
introduced zone finishing code both for data and metadata end_io path.
However, the metadata side is not working as it should. First, it
compares logical address (eb->start + eb->len) with offset within a
block group (cache->zone_capacity) in submit_eb_page(). That essentially
disabled zone finishing on metadata end_io path.

Furthermore, fixing the issue above revealed we cannot call
btrfs_zone_finish_endio() in end_extent_buffer_writeback(). We cannot
call btrfs_lookup_block_group() which require spin lock inside end_io
context.

Introduce btrfs_schedule_zone_finish_bg() to wait for the extent buffer
writeback and do the zone finish IO in a workqueue.

Also, drop EXTENT_BUFFER_ZONE_FINISH as it is no longer used.

btrfs: zoned: finish block group when there are no more allocatable bytes left · 8b8a5399

由 Naohiro Aota 提交于 5月 03, 2022

Currently, btrfs_zone_finish_endio() finishes a block group only when the
written region reaches the end of the block group. We can also finish the
block group when no more allocation is possible.

btrfs: improve error reporting in lookup_inline_extent_backref · cf4f03c3

由 Nikolay Borisov 提交于 4月 29, 2022

When iterating the backrefs in an extent item if the ptr to the
'current' backref record goes beyond the extent item a warning is
generated and -ENOENT is returned. However what's more appropriate to
debug such cases would be to return EUCLEAN and also print identifying
information about the performed search as well as the current content of
the leaf containing the possibly corrupted extent item.
