[PATCH 01/11] libxfs: remove i_transp

Subject: [PATCH 01/11] libxfs: remove i_transp
Date: Fri, 10 May 2019 15:18:20 -0500	[thread overview]
Message-ID: <1557519510-10602-2-git-send-email-sandeen@redhat.com> (raw)
In-Reply-To: <1557519510-10602-1-git-send-email-sandeen@redhat.com>

i_transp was removed from kernel code back in 2011, but it was left
in userspace.  It's only used in a few asserts in transaction code
(as it was in the kernel) so there doesnt' seem to be a compelling
reason to carry it around anymore.

Source kernel commit: f3ca87389dbff0a3dc1a7cb2fa7c62e25421c66c
