Fix the heading and Size/Used/Priority field alignments in /proc/swaps. If the Size and/or Used value is >= 10000000 (8 bytes), then the alignment by using tab characters is broken. This patch maintains the use of tabs for alignment. If spaces are preferred, we can just use a Field Width specifier for the bytes and inuse fields. That way those fields don't have to be a multiple of 8 bytes in width. E.g., with a field width of 12, both Size and Used would always fit on the first line of an 80-column wide terminal (only Priority would be on the second line). There are actually 2 problems: heading alignment and field width. On an xterm, if Used is 7 bytes in length, the tab does nothing, and the display is like this, with no space/tab between the Used and Priority fields. (ugh) Filename Type Size Used Priority /dev/sda8 partition 16779260 2023012-1 To be clear, if one does 'cat /proc/swaps >/tmp/proc.swaps', it does look different, like so: Filename Type Size Used Priority /dev/sda8 partition 16779260 2086988 -1 Signed-off-by: Randy Dunlap <rdunlap@infradead.org> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Reviewed-by: Andrew Morton <akpm@linux-foundation.org> Cc: Hugh Dickins <hughd@google.com> Cc: Alexander Viro <viro@zeniv.linux.org.uk> Link: http://lkml.kernel.org/r/c0ffb41a-81ac-ddfa-d452-a9229ecc0387@infradead.org Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> |

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.
