After s_error_count is incremented, signal the change in the corresponding sysfs attribute via sysfs_notify. This allows userspace to poll() on changes to /sys/fs/ext4/*/errors_count. [ Moved call of ext4_notify_error_sysfs() to flush_stashed_error_work() to avoid BUG's caused by calling sysfs_notify trying to sleep after being called from an invalid context. -- TYT ] Signed-off-by: Jonathan Davies <jonathan.davies@nutanix.com> Link: https://lore.kernel.org/r/20210611140209.28903-1-jonathan.davies@nutanix.com Signed-off-by: Theodore Ts'o <tytso@mit.edu>
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.
