We currently have hundreds of proc files that implement plain, read-only seq_file based interfaces. This series consolidates them using new procfs helpers that take the seq_operations or simple show callback directly. A git tree is available at: git://git.infradead.org/users/hch/misc.git proc_create.2 Gitweb: http://git.infradead.org/users/hch/misc.git/shortlog/refs/heads/proc_create.2 Changes since V1: - open code proc_create_data to avoid setting not fully initialized entries live - use unsigned int for state_size - dropped the s390/cio/blacklist hunk as it has a write method - dropped the IPMI patch given that IPMI proc support is scheduled for removal.
