Hi, Christian Hi, Christoph Hi, Jan Perhaps now is a good time to send a formal version of this set. However, I'm not sure yet what branch should I rebase and send this set. Should I send to the vfs tree? Thanks, Kuai 在 2024/02/22 20:45, Yu Kuai 写道:
From: Yu Kuai <yukuai3@xxxxxxxxxx> Changes in v4: - respin on the top of linux-next, based on Christian's patchset to open bdev as file. Most of patches from v3 is dropped and change to use file_inode(bdev_file) to get bd_inode or bdev_file->f_mapping to get bd_inode->i_mapping. Changes in v3: - remove bdev_associated_mapping() and patch 12 from v1; - add kerneldoc comments for new bdev apis; - rename __bdev_get_folio() to bdev_get_folio; - fix a problem in erofs that erofs_init_metabuf() is not always called. - add reviewed-by tag for patch 15-17; Changes in v2: - remove some bdev apis that is not necessary; - pass in offset for bdev_read_folio() and __bdev_get_folio(); - remove bdev_gfp_constraint() and add a new helper in fs/buffer.c to prevent access bd_indoe() directly from mapping_gfp_constraint() in ext4.(patch 15, 16); - remove block_device_ejected() from ext4.
