[LU-10937] Use sysfs to fix up sptlrpc handling.

• Type: Bug
• Resolution: Unresolved
• Priority: Major
• Affects Version/s: Lustre 2.12.0
• Environment: Lustre with sptlrpc/gss enabled.
• Severity: 3
• Assignee: James A Simmons
• Reporter: James A Simmons

Description

Several problems exist for the GSS / sptlrpc code. The problems are:

1) lctl set_param  P does not work with sptlrpc  LU-7183

2) Specific mgs bingings for sptlrpc is broken. LU-9034 / LU-9086 / LU-9567

    With the move to kobjects with sysfs we could the kobject instead.

3) After the move to sysfs we can use udev events instead of polling the proc files like what is now done in for example svgssd.
