This adds missing iomap flags to IOMAP_FLAGS_STRINGS & IOMAP_F_FLAGS_STRINGS for tracing. While we are at it, let's also print values of iomap->type & iomap->flags. e.g. trace for ATOMIC_BIO flag set xfs_io-1203 [000] ..... 183.001559: iomap_iter_dstmap: dev 8:32 ino 0xc bdev 8:32 addr 0x84200000 offset 0x0 length 0x10000 type MAPPED (0x2) flags DIRTY|ATOMIC_BIO (0x102) e.g. trace with DONTCACHE flag set xfs_io-1110 [007] ..... 238.780532: iomap_iter: dev 8:16 ino 0x83 pos 0x1000 length 0x1000 status 0 flags WRITE|DONTCACHE (0x401) ops xfs_buffered_write_iomap_ops caller iomap_file_buffered_write+0xab/0x0 Reviewed-by: "Darrick J.

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 reStructuredText 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.
