So, I take that back, one of these decompress patches is causing this:
[root@five ~]# perf list syscalls:sys_enter_open |& tail lzma: fopen failed on /usr/lib/modules/5.6.19-200.fc31.x86_64/kernel/drivers/acpi/video.ko.xz: 'No such file or directory' lzma: fopen failed on /usr/lib/modules/5.5.8-200.fc31.x86_64/kernel/net/ipv4/netfilter/nf_reject_ipv4.ko.xz: 'No such file or directory' lzma: fopen failed on /usr/lib/modules/5.5.9-200.fc31.x86_64/kernel/net/ipv6/netfilter/ip6_tables.ko.xz: 'No such file or directory' lzma: fopen failed on /usr/lib/modules/5.5.5-200.fc31.x86_64/kernel/drivers/crypto/ccp/ccp.ko.xz: 'No such file or directory' lzma: fopen failed on /usr/lib/modules/5.4.20-200.fc31.x86_64/kernel/sound/pci/hda/snd-hda-codec.ko.xz: 'No such file or directory' lzma: fopen failed on /usr/lib/modules/5.5.15-200.fc31.x86_64/kernel/drivers/target/target_core_mod.ko.xz: 'No such file or directory' lzma: fopen failed on /usr/lib/modules/5.3.7-301.fc31.x86_64/kernel/drivers/iommu/amd_iommu_v2.ko.xz: 'No such file or directory' lzma: fopen failed on /usr/lib/modules/5.3.7-301.fc31.x86_64/kernel/drivers/media/v4l2-core/videodev.ko.xz: 'No such file or directory' lzma: fopen failed on /usr/lib/modules/5.6.19-200.fc31.x86_64/kernel/net/ipv4/netfilter/iptable_filter.ko.xz: 'No such file or directory' syscalls:sys_enter_open [Tracepoint event] [root@five ~]# perf test 78 78: Check open filename arg using perf trace + vfs_getname : FAILED! [root@five ~]# [root@five ~]# uname -a Linux five 5.9.0-rc3 #1 SMP Mon Aug 31 08:38:27 -03 2020 x86_64 x86_64 x86_64 GNU/Linux [root@five ~]#
So I removed them from my local branch, I'll rerun the build tests and then push perf/core when all tests pass.
The test uses 'perf probe' and I noticed it when processing Masami's debuginfod patches to make 'perf probe' use it, I thought it was his patches, looking only at the 'perf test 78' output, but ended up being the decompress ones.
