Hi all,
This is the initial patchset based on feedbacks from the RFC patcheset [1].
Its main purpose is adding customizable default values for XFS error
configuration, so a default value can be configured for all XFS filesystems
at one time.
A sysfs tree is created under .../xfs/default_error and its hierarchies are
the same with the tree under .../fs/xfs/<dev>/error. The main change is the
implementation method of the default error configuration. In the RFC patchset,
a modify-and-notify method is used. Now, a distinct flag is kept for each
fs-specific error configuration. The flag denotes the error configuration has
a no-default value, and it will be set when a value of no-"default" is written
to the corresponding sysfs file, and will be cleared when a value of "default"
is wrote. These flags will checked by xfs_error_get_cfg() when returning an
error configuration to XFS error handler.
Other changes include adding an extra sysfs attribute named summary to assist
the test of error configuration ("default" vs no-"default") and updating the
documentation accordingly.
Thoughts, reviews, flames appreciated.
