A local format symlink inode is converted to extent format when an extended attribute is set on an inode as part of the attribute fork creation. This means a block is allocated, the local symlink target name is copied to the block and the block is logged. Currently, xfs_bmap_local_to_extents() handles logging the remote block data based on the size of the data fork prior to the conversion. This is not correct on v5 superblock filesystems, which add an additional header to remote symlink blocks that is nonexistent in local format inodes. As a result, the full length of the remote symlink block content is not logged. This can lead to corruption should a crash occur and log recovery replay this transaction. Since a callout is already used to initialize the new remote symlink block, update the local-to-extents conversion mechanism to make the callout also responsible for logging the block. It is already required to set the log buffer type and format the block appropriately based on the superblock version. This ensures the remote symlink is always logged correctly. Note that xfs_bmap_local_to_extents() is only called for symlinks so there are no other callouts that require modification.
