Whenever we encounter corrupt fs metadata, we should report that to the
health monitoring system for later reporting. A convenient program for
identifying places to insert xfs_*_mark_sick calls is as follows:
#!/bin/bash
# Detect missing calls to xfs_*_mark_sick
filter=cat
tty -s && filter=less
git grep -B3 EFSCORRUPTED fs/xfs/*.[ch] fs/xfs/libxfs/*.[ch] fs/xfs/scrub/*.[ch] | awk '
BEGIN {
ignore = 0;
lineno = 0;
delete lines;
}
{
if ($0 == "--") {
if (!ignore) {
for (i = 0; i < lineno; i++) {
print(lines[i]);
}
printf("--\n");
}
delete lines;
lineno = 0;
ignore = 0;
} else if ($0 ~ /mark_sick/) {
ignore = 1;
} else if ($0 ~ /if .fa/) {
ignore = 1;
} else if ($0 ~ /failaddr/) {
ignore = 1;
} else if ($0 ~ /_verifier_error/) {
ignore = 1;
} else if ($0 ~ /^ \* .*EFSCORRUPTED/) {
ignore = 1;
} else if ($0 ~ /== -EFSCORRUPTED/) {
ignore = 1;
} else if ($0 ~ /!= -EFSCORRUPTED/) {
ignore = 1;
} else {
lines[lineno++] = $0;
}
}

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.
