      sysfs, kernfs: make inode number ida per kernfs_root · bc755553
      Tejun Heo 提交于
      kernfs is being updated to allow multiple sysfs_dirent hierarchies so
      that it can also be used by other users.  Currently, inode number is
      allocated using a global ida, sysfs_ino_ida; however, inos for
      different hierarchies should be handled separately.
      
      This patch makes ino allocation per kernfs_root.  sysfs_ino_ida is
      replaced by kernfs_root->ino_ida and sysfs_new_dirent() is updated to
      take @root and allocate ino from it.  ida_simple_get/remove() are used
      instead of sysfs_ino_lock and sysfs_alloc/free_ino().

      sysfs, kernfs: move file core code to fs/kernfs/file.c · 414985ae
      Tejun Heo 提交于
      Move core file code to fs/kernfs/file.c.  fs/sysfs/file.c now contains
      sysfs kernfs_ops callbacks, sysfs wrappers around kernfs interfaces,
      and sysfs_schedule_callback().  The respective declarations in
      fs/sysfs/sysfs.h are moved to fs/kernfs/kernfs-internal.h.
      
      This is pure relocation.
      
      v2: Refreshed on top of the v2 of "sysfs, kernfs: prepare read path
          for kernfs".

      sysfs, kernfs: add skeletons for kernfs · b8441ed2
      Tejun Heo 提交于
      Core sysfs implementation will be separated into kernfs so that it can
      be used by other non-kobject users.
      
      This patch creates fs/kernfs/ directory and makes boilerplate changes.
      kernfs interface will be directly based on sysfs_dirent and its
      forward declaration is moved to include/linux/kernfs.h which is
      included from include/linux/sysfs.h.  sysfs core implementation will
      be gradually separated out and moved to kernfs.
      
      This patch doesn't introduce any functional changes.
      
      v2: mount.c added.
