fsnotify_unmount_inodes

Name:snotify_unmount_inodes - an sb is unmounting. handle any watched inodes.*@sb: superblock being unmounted.* Called during unmount with no locks held, so needs to be safe against* concurrent modifiers. We temporarily drop sb->s_inode_list_lock and CAN block.

Proto:static void fsnotify_unmount_inodes(struct super_block *sb)

Type:void

This is the main call to fsnotify. The VFS calls into hook specific functions* in linux/fsnotify.h. Those functions then in turn call here. Here will call* out to all of the registered fsnotify_group. Those groups can then use the
