OpenZFS exceptions

Commit exceptions used to explicitly reference a given Linux commit. These exceptions are useful for a variety of reasons.

This page is used to generate OpenZFS Tracking page.

Format:

• <openzfs issue>|-|<comment> - The OpenZFS commit isn't applicable to Linux, or the OpenZFS -> ZFS on Linux commit matching is unable to associate the related commits due to lack of information (denoted by a -).
• <openzfs issue>|<commit>|<comment> - The fix was merged to Linux prior to their being an OpenZFS issue.
• <openzfs issue>|!|<comment> - The commit is applicable but not applied for the reason described in the comment.
