[dpdk-dev] [PATCH] nfp: restore the unlink operation

[dpdk-dev] [PATCH] nfp: restore the unlink operation

[Aaron Conole]

For the stable versions of DPDK, the NFP driver's NSP user space
driver was modified to account for non-root usage.  When that
happened, commit 515933ad8385 ("nfp: allow for non-root user")
inadvertently removed the unlink() call.

This patch is for stable tree.

Which stable branches are effected? Only 18.02?


And a generic stable tree question, is there a easy way to find out which stable
versions has a fix? For this example which versions get "nfp: allow for non-root
user" fix?

I'm not sure if there is something in
http://dpdk.org/browse/tools/stable-scripts/ that might automatically
find the dependency?

Applied and pushed to stable/18.02

Next time, please send patches that are only for stable to stable@dpdk.
org and do not include dev@dpdk.org
Also use --subject-prefix='PATCH <branch>' so that we can understand
for which branches a patch is
