-Subject: [PATCH] misc: rename copy_file_range to copy_file_chunk
-
-As of 2.27, glibc will have a copy_file_range library call to wrap the
-new copy_file_range system call.  This conflicts with the function in
-misc/create_inode.c, which this patch renames _copy_file_range.

-Subject: [PATCH] ARM: Don't extend bit LG_VADDR to compute high address bits.
-
-In userspace ARM on Linux, zero-ing the high bits is the correct way to do this.
-This doesn't fix the fact that we currently set LG_VADDR to 48 on ARM, when in
-fact larger virtual address sizes are coming soon.  We'll cross that bridge when
-we come to it.

-Subject: Prevent directory chmod race attack.
-
-CVE-2017-6512 is a race condition attack where the chmod() of directories
-that cannot be entered is misused to change the permissions on other
-files or directories on the system. This has been corrected by limiting
-the directory-permission loosening logic to systems where fchmod() is
-supported.
-
-[Backported (whitespace adjustments) to File-Path 2.12 / perl 5.24 by
-Dominic Hargreaves for Debian.]
