injection testing. Change ext4's fallocate to update consistently drop set[ug]id bits when an fallocate operation might possibly change the user-visible contents of a file. Also, improve handling of potentially invalid values in the the s_overhead_cluster superblock field to avoid ext4 returning a negative number of free blocks. -----BEGIN PGP SIGNATURE----- iQEzBAABCAAdFiEEK2m5VNv+CHkogTfJ8vlZVpUNgaMFAmJinf8ACgkQ8vlZVpUN gaOHgQf+MKgUZgteYogLzoP3mF1kSycOGawk4wZ3QHOLz7AvsV2p9J8BWihbS/EK dBydfXbTMvCUrjWmpqb5dHECRzxdfxOJ0SPJtibc8DZaJc9ImNFmgSp9kyJ3uRaN cPGO6Lz2RXpdumVMPPLwzUJdVyrLi0K6I1NYSocxKgribePzd+xil8S9zRZj8Bpe RaeH0EytcRj2CI5qs5mI/mOPBAMsZeczd3HInI3gyCgP2I4ZOfsADne3APx57mcI IGKf77nvIwMHeKel3MGYfFPitEs5cZpHUhHplCMtgFsO8H0IR93tqnlaCvTM7VAZ Slamgl7pfcXFcLZP+pm0QL/82ub7iw== =FIds -----END PGP SIGNATURE----- Merge tag 'ext4_for_linus_stable' of git://git.kernel.org/pub/scm/linux/kernel/git/tytso/ext4 Pull ext4 fixes from Ted Ts'o: "Fix some syzbot-detected bugs, as well as other bugs found by I/O injection testing.

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.
