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.

This functionality could be ported but it's unclear to what purpose. 7542|- |The Linux libshare code differs significantly from the upstream OpenZFS code. Since this change doesn't address a Linux specific issue it doesn't need to be ported.

This patch could still be applied to minimize code delta or all HAVE_IDMAP chunks could be removed on Linux for better readability. 5313|ec8501e| 5312|! |This change should be made but the ideal time to do it is when the spl repository is folded in to the zfs repository (planned for 0.8).
