Merge tag 'v4.0-rc1' into patchwork
Linux 34.0-rc1 * tag 'v4.0-rc1': (8947 commits) Linux 4.0-rc1 autofs4 copy_dev_ioctl(): keep the value of ->size we'd used for allocation procfs: fix race between symlink removals and traversals debugfs: leave freeing a symlink body until inode eviction Documentation/filesystems/Locking: ->get_sb() is long gone trylock_super(): replacement for grab_super_passive() fanotify: Fix up scripted S_ISDIR/S_ISREG/S_ISLNK conversions Cachefiles: Fix up scripted S_ISDIR/S_ISREG/S_ISLNK conversions VFS: (Scripted) Convert S_ISLNK/DIR/REG(dentry->d_inode) to d_is_*(dentry) SELinux: Use d_is_positive() rather than testing dentry->d_inode Smack: Use d_is_positive() rather than testing dentry->d_inode TOMOYO: Use d_is_dir() rather than d_inode and S_ISDIR() Apparmor: Use d_is_positive/negative() rather than testing dentry->d_inode Apparmor: mediated_filesystem() should use dentry->d_sb not inode->i_sb VFS: Split DCACHE_FILE_TYPE into regular and special types VFS: Add a fallthrough flag for marking virtual dentries VFS: Add a whiteout dentry type VFS: Introduce inode-getting helpers for layered/unioned fs environments kernel: make READ_ONCE() valid on const arguments blk-throttle: check stats_cpu before reading it from sysfs ...
