Instead of a page, use a folio for btrfs_writepage_cow_fixup. We already have a folio at the only caller, and the fixup worker uses folios. Signed-off-by:

Instead of passing in the page for ->locked_page, make it hold a locked_folio and then update the users of async_chunk to act accordingly. Signed-off-by:

Now that every function that btrfs_run_delalloc_range calls takes a folio, update it to take a folio and update the callers. Signed-off-by:

This just passes the page into the compressed machinery to keep track of the locked page. Update this to take a folio and convert it to a page where appropriate. Signed-off-by:

We walk through pages in this function and clear ordered, and the function for this uses folios. Update the function to use a folio for this whole operation. Signed-off-by:

Now all of the functions that use locked_page in run_delalloc_nocow take a folio, update it to take a folio and update the caller. Signed-off-by:

With this we can pass the folio directly into cow_file_range(). Signed-off-by:

Convert this to take a folio and pass it into all of the various cleanup functions. Update the callers to pass in a folio instead. Signed-off-by:

Now that we want the folio in this function, convert it to take a folio directly and use that. Signed-off-by:

We pass the folio into extent_write_locked_range, go ahead and take a folio to pass along, and update the callers to pass in a folio. Signed-off-by:

Instead of taking the locked page, take the locked folio so we can pass that into __process_folios_contig. Signed-off-by:

Now that this mostly uses folios, update it to take folios, use the folios that are passed in, and rename from process_one_page => process_one_folio. Signed-off-by:

This operates mostly on folios, update it to take a folio for the locked folio instead of the page, rename from __process_pages_contig => __process_folios_contig. Signed-off-by:

All of the callers have a folio at this point, update __unlock_for_delalloc to take a folio so that it's consistent with its callers. Signed-off-by:

Also rename lock_delalloc_pages => lock_delalloc_folios in the process, now that it exclusively works on folios. Signed-off-by:

Josef Bacik authored
Instead of passing in a page for locked_page, pass in the folio instead. We only use the folio itself to validate some range assumptions, and then pass it into other functions. Signed-off-by:

We already use a folio heavily in this function, pass the folio in directly and use it everywhere, only passing the page down to functions that do not take a folio yet. Signed-off-by:

We only need a folio now, make it take a folio as an argument and update all of the callers. Signed-off-by:

We already have a folio that we're using in btrfs_page_mkwrite, update the rest of the function to use folio everywhere else. This will make it easier on Willy when he drops page->index. Signed-off-by:

Josef Bacik authored
Willy is going to get rid of page->index, and add_ra_bio_pages uses page->index. Make his life easier by converting add_ra_bio_pages to use folios so that we are no longer using page->index. Signed-off-by:

Now that we've gotten most of the helpers updated to only take a folio, update __extent_writepage to only deal in folios. Signed-off-by:

Instead of using pages for everything, find a folio and use that. This makes things a bit cleaner as a lot of the functions calls here all take folios. Signed-off-by:

__extent_writepage_io uses page everywhere, but a lot of these functions take a folio. Convert it to use the folio based helpers, and then change it to take a folio as an argument and update its callers. Signed-off-by:

Now that the callers and helpers mostly use folio, convert btrfs_do_readpage to take a folio, and rename it to btrfs_do_read_folio. Update all of the page stuff to use the folio based helpers instead. Signed-off-by:

The callers of this helper are going to be converted to using a folio, so adjust submit_extent_page to become submit_extent_folio and update it to use all the relevant folio helpers. Signed-off-by:

This already uses a folio internally, change it to take a folio as an argument instead. Signed-off-by:

We have this helper function to set the page range uptodate once we're done reading it, as well as run fsverity against it. Half of these functions already take a folio, just rename this to end_folio_read and then rework it to take a folio instead, and update everything accordingly. Signed-off-by:

[ENHANCEMENT] When mounting a btrfs filesystem, the filesystem opens the block device, and if this fails, there is no message about it. Print a message about it to help debugging. [TEST] I have a btrfs filesystem on three block devices, one of which is write-protected, so regular mounts fail, but there is no message in dmesg. /dev/vdb normal /dev/vdc write protected /dev/vdd normal Before patch: $ sudo mount /dev/vdb /mnt/ mount: mount(2) failed: no such file or directory $ sudo dmesg # Show only messages about missing block devices ....

At extent_map_block_end() we are calling the inline functions extent_map_block_start() and extent_map_block_len() multiple times, which results in expanding their code multiple times, increasing the compiled code size and repeating the computations those functions do. Improve this by caching their results in local variables. The size of the module before this change: $ size fs/btrfs/btrfs.ko text data bss dec hex filename 1755770 163800 16920 1936490 1d8c6a fs/btrfs/btrfs.ko And after this change: $ size fs/btrfs/btrfs.ko text data bss dec hex filename 1755656 163800 16920 1936376 1d8bf8 fs/btrfs/btrfs.ko Reviewed-by:Filipe Manana <fdmanana@suse.com> Reviewed-by:
