Merge patch series "fs: Move metadata bh tracking from address_space"

Jan Kara <jack@suse.cz> says: This patch series cleans up the mess that has accumulated over the years in metadata buffer_head tracking for inodes, moves the tracking into dedicated structure in filesystem-private part of the inode (so that we don't use private_list, private_data, and private_lock in struct address_space), and also moves couple other users of private_data and private_list so these are removed from struct address_space saving 3 longs in struct inode for 99% of inodes. I would like to get rid of private_lock in struct address_space as well however the locking changes for buffer_heads are non-trivial there and the patch series is long enough as is. So let's leave that for another time. * patches from https://patch.msgid.link/20260326082428.31660-1-jack@suse.cz: (42 commits) fs: Drop i_private_list from address_space fs: Drop mapping_metadata_bhs from address space ext4: Track metadata bhs in fs-private inode part minix: Track metadata bhs in fs-private inode part udf: Track metadata bhs in fs-private inode part fat: Track metadata bhs in fs-private inode part bfs: Track metadata bhs in fs-private inode part affs: Track metadata bhs in fs-private inode part ext2: Track metadata bhs in fs-private inode part fs: Provide functions for handling mapping_metadata_bhs directly fs: Switch inode_has_buffers() to take mapping_metadata_bhs fs: Make bhs point to mapping_metadata_bhs fs: Move metadata bhs tracking to a separate struct fs: Fold fsync_buffers_list() into sync_mapping_buffers() fs: Drop osync_buffers_list() kvm: Use private inode list instead of i_private_list fs: Remove i_private_data aio: Stop using i_private_data and i_private_lock hugetlbfs: Stop using i_private_data fs: Stop using i_private_data for metadata bh tracking ...
