-Subject: [PATCH] tests/ioctl_kvm_run.c: handle cpuid at the end of vcpu dentry
-
-Since Linux 4.16, kernel appends the cpuid as suffix to the entry
-for a kvm vcpu in /proc/$pid/fd like:
-
- anon_inode:kvm-vcpu:0
-
-That was
-
- anon_inode:kvm-vcpu
-
-This kernel change causes the test case failure on newer kernels.
-Update the test to deal with the new name as well as the old one.
-
-* tests/ioctl_kvm_run.c: Include unistd.h for using readlink(2).
-(vcpu_dev_should_have_cpuid): New function for detecting whether
-a proc entry for given fd has the cpuid suffix or not.
-(main): Trim vcpu_dev to remove the cpuid suffix if needed.
-(vcpu_dev): Remove const modifier.
