Applied to cosmic master-next. Unstable already has it. Thanks. Cascardo. Applied-to: cosmic/master-next
BugLink: https://bugs.launchpad.net/bugs/1793086 == SRU Justification == IBM reports the qethqoat tool fails. qeth_query_oat_command() currently allocates the kernel buffer for the SIOC_QETH_QUERY_OAT ioctl with kzalloc. This commit will cause the use of vzalloc() instead of kzalloc(), backing the allocation with non-contiguous memory. Xenial also needs this commit, but requres a slightly different backport. It's SRU will be sent separate. == Fix == aec45e857c55 ("s390/qeth: use vzalloc for QUERY OAT buffer") == Regression Potential == Low, limited to s390. == Test Case == IBM verified testing of this commit up-front.
