[f2fs-dev] [PATCH 000/153] f2fs folio conversions for 6.16

[f2fs-dev] [PATCH 000/153] f2fs folio conversions for 6.16

[Matthew Wilcox (Oracle)]

Sorry for the length of this series.  Each patch in this series builds,
but obviously I haven't done any testing.  It should be easy to bisect
to any mistakes I've made.  This conversion isn't complete; I estimate
another 100 or so patches will be needed.

Matthew Wilcox (Oracle) (153):

[f2fs-dev] [PATCH 001/153] f2fs: Use a folio in f2fs_compress_free_page()

[Matthew Wilcox (Oracle)]

Convert the incoming page to a folio and operate on it.  Removes a
reference to page->mapping which is going away soon.

[f2fs-dev] [PATCH 002/153] f2fs: Use a folio in f2fs_write_raw_pages()

[Matthew Wilcox (Oracle)]

Convert each page in rpages to a folio before operating on it.  Replaces
eight calls to compound_head() with one and removes a reference to
page->mapping which is going away soon.

[f2fs-dev] [PATCH 003/153] f2fs: Introduce fio_inode()

[Matthew Wilcox (Oracle)]

This helper returns the inode associated with the f2fs_io_info.  That's a
relatively common thing to want, mildly awkward to get and provides one
place to change if we decide to record it directly, or change fio->page
to fio->folio.

[f2fs-dev] [PATCH 005/153] f2fs: Use bio_for_each_folio_all() in __has_merged_page()

[Matthew Wilcox (Oracle)]

Iterate over each folio rather than each page.  Convert
f2fs_compress_control_page() to f2fs_compress_control_folio() since
this is the only caller.  Removes a reference to page->mapping which
is going away soon as well as calls to fscrypt_is_bounce_page() and
fscrypt_pagecache_page().

[f2fs-dev] [PATCH 006/153] f2fs: Use a folio in add_ipu_page()

[Matthew Wilcox (Oracle)]

Convert the incoming page to a folio at the start, then use the
folio later in the function.  Moves a call to page_folio() earlier,
and removes an access to page->mapping.

[f2fs-dev] [PATCH 009/153] f2fs: Use a folio in f2fs_quota_read()

[Matthew Wilcox (Oracle)]

Support arbitrary size folios and remove a few hidden calls to
compound_head().  Also remove an unnecessary test of the uptodaate flag;
if mapping_read_folio_gfp() cannot bring the folio uptodate, it will
return an error.

f2fs_grab_meta_folio() and writeback can't have restarted in the

[f2fs-dev] [PATCH 013/153] f2fs: Use f2fs_folio_wait_writeback()

[Matthew Wilcox (Oracle)]

There were some missing conversions from f2fs_wait_on_page_writeback()
to f2fs_folio_wait_writeback().  Saves a call to compound_head() at each
callsite.

[f2fs-dev] [PATCH 014/153] f2fs: Pass a folio to f2fs_submit_merged_ipu_write()

[Matthew Wilcox (Oracle)]

The only caller which passes a page already has a folio, so pass
it in.

[f2fs-dev] [PATCH 017/153] f2fs: Pass a folio to next_blkaddr_of_node()

[Matthew Wilcox (Oracle)]

Pass the folio into sanity_check_node_footer() so that we can pass
it further into next_blkaddr_of_node().  Removes a lot of conversions
from folio->page.

[f2fs-dev] [PATCH 019/153] f2fs: Use a folio in f2fs_ra_meta_pages_cond()

[Matthew Wilcox (Oracle)]

Remove a call to find_get_page().  Saves two hidden calls to
compound_head().  Change f2fs_folio_put() to check for IS_ERR_OR_NULL
to handle the case where we got an error pointer back from
filemap_get_folio().

[f2fs-dev] [PATCH 051/153] highmem: Add memcpy_folio()

[Matthew Wilcox (Oracle)]

The folio equivalent of memcpy_page().  It should correctly and
efficiently manage large folios:

 - If one, neither or both is highmem
 - If (either or both) offset+len crosses a page boundary
 - If the two offsets are congruent or not

[f2fs-dev] [PATCH 067/153] f2fs: Pass a folio to f2fs_inode_chksum_verify()

[Matthew Wilcox (Oracle)]

Both callers now have a folio, so pass it in.  Removes three calls
to compound_head().

[f2fs-dev] [PATCH 074/153] f2fs: Use folios in f2fs_get_dnode_of_data()

[Matthew Wilcox (Oracle)]

Pass the folio into __get_node_folio() and f2fs_get_node_page_ra() which
becomes f2fs_get_node_folio_ra().  That function has no callers outside
node.c, so make it static.  Removes seven calls to compound_head().

[f2fs-dev] [PATCH 108/153] f2fs: Pass folios to f2fs_init_acl()

[Matthew Wilcox (Oracle)]

The one caller already has folios, so pass them in, and further pass
them to __f2fs_set_acl() and f2fs_acl_create().  There should be
no change to the generated code for this commit.

[f2fs-dev] [PATCH 115/153] f2fs: Pass a folio to f2fs_getxattr()

[Matthew Wilcox (Oracle)]

The one caller of __f2fs_get_acl() which passes a non-NULL page already
has a folio, so pass it in, then into f2fs_getxattr(), which lets us
pass it to lookup_all_xattrs().

[f2fs-dev] [PATCH 127/153] f2fs: Pass a folio to f2fs_find_entry()

[Matthew Wilcox (Oracle)]

Convert all callers to pass in a pointer to a folio instead of a page.
Also convert f2fs_inode_by_name() to take a folio pointer.  Removes
six calls to compound_head().

[f2fs-dev] [PATCH 138/153] f2fs: Use a folio in f2fs_cache_compressed_page()

[Matthew Wilcox (Oracle)]

Look up a folio instead of a page, and if that fails, allocate a folio.
Removes five calls to compound_head(), one of the last few references to
add_to_page_cache_lru() and honours the cpuset_do_page_mem_spread()
setting.

[f2fs-dev] [PATCH 139/153] f2fs: Use a folio in prepare_compress_overwrite()

[Matthew Wilcox (Oracle)]

Add f2fs_filemap_get_folio() as a wrapper around __filemap_get_folio()

[f2fs-dev] [PATCH 148/153] f2fs: Convert dnode_of_data->node_page to node_folio

[Matthew Wilcox (Oracle)]

All assignments to this struct member are conversions from a folio
so convert it to be a folio and convert all users.  At the same time,
convert data_blkaddr() to take a folio as all callers now have a folio.
Remove eight calls to compound_head().

[f2fs-dev] [PATCH 149/153] f2fs: Pass a folio to get_dnode_addr()

[Matthew Wilcox (Oracle)]

All callers except __get_inode_rdev() and __set_inode_rdev() now have a
folio, but the only callers of those two functions do have a folio, so
pass the folio to them and then into get_dnode_addr().

[f2fs-dev] [PATCH 153/153] f2fs: Convert clear_node_page_dirty() to clear_node_folio_dirty()

[Matthew Wilcox (Oracle)]

Both callers have a folio so pass it in, removing five calls to
compound_head().

Oh, I missed that f2fs_folio_put() can handle error and NULL folio,
please ignore this.

Thanks for the work, the patchset looks good to me.

Reviewed-by: Chao Yu <chao@kernel.org>

Note that, it needs to clean up f2fs_put_page(, {0,1}) w/
f2fs_folio_put(, {false,true}), I guess Jaegeuk could help to update
directly in dev-test branch?

Thanks,
