jbd2/ocfs2: Fix block checksumming when a buffer is used in several transactions
This is a request to include an upstream patch in the upcoming RHEL6 kernel.
This issue has been proposed when we are only considering blocker
issues in the current Red Hat Enterprise Linux release.
** If you would still like this issue considered for the current
release, ask your support representative to file as a blocker on
your behalf. Otherwise ask that it be considered for the next
Red Hat Enterprise Linux release. **
Not sure I understand what next refers to. 6.1?
If so, adding this change then will be expensive because it breaks abi. Easier to do it now.
The patch is safe. While it modifies jbd2, it modifies a functionality that ext4 does not use. In fact, if you ignore the change in the function name, the actual diff is very small.
ocfs2 needs this patch inorder to support metaecc (metadata checksumming).
Hrm that isn't clear is it, yeah it's talking about 6.1. JBD/JBD2 are not bound by KABI, so we can change whatever we want, whenever we want, so 6.1 is reasonable.
This request was evaluated by Red Hat Product Management for inclusion
in a Red Hat Enterprise Linux maintenance release. Product Management has
requested further review of this request by Red Hat Engineering, for potential
inclusion in a Red Hat Enterprise Linux Update release for currently deployed
products. This request is not yet committed for inclusion in an Update release.
Patch(es) available on kernel-2.6.32-130.el6
