Subject: [PATCH] Revert Consolidate arc_buf allocation checks
|
||||
|
||||
This reverts commit 13fac09868b4e4e08cc3ef7b937ac277c1c407b1.
|
||||
|
||||
Per the discussion in #11531, the reverted commit---which intended only
|
||||
to be a cleanup commit---introduced a subtle, unintended change in
|
||||
behavior.
|
||||
|
||||
Care was taken to partially revert and then reapply 10b3c7f5e4
|
||||
which would otherwise have caused a conflict. These changes were
|
||||
squashed in to this commit.
