From 73d9714627adced2942e8d53ce0e73d9699a996c Mon Sep 17 00:00:00 2001 From: Tejun Heo Date: Tue, 1 Oct 2013 17:42:07 -0400 Subject: sysfs: copy bin mmap support from fs/sysfs/bin.c to fs/sysfs/file.c sysfs bin file handling will be merged into the regular file support. This patch copies mmap support from bin so that fs/sysfs/file.c can handle mmapping bin files. The code is copied mostly verbatim with the following updates. * ->mmapped and ->vm_ops are added to sysfs_open_file and bin_buffer references are replaced with sysfs_open_file ones. * Symbols are prefixed with sysfs_. * sysfs_unmap_bin_file() grabs sysfs_open_dirent and traverses ->files. Invocation of this function is added to sysfs_addrm_finish(). * sysfs_bin_mmap() is added to sysfs_bin_operations. This is a preparation and the new mmap path isn't used yet.
