Linux kernel source tree

Prevent exec continuing when a fatal signal is pending by replacing mmap_read_lock with mmap_read_lock_killable. This is always the right thing to do as userspace will never observe an exec complete when there is a fatal signal pending. With that change it becomes unnecessary to explicitly test for a core dump in progress. In coredump_wait zap_threads arranges under mmap_write_lock for all tasks that use a mm to also have SIGKILL pending, which means mmap_read_lock_killable will always return -EINTR when old_mm->core_state is present.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
