What were you trying to do that didn't work?
When compiling a reproducer test case, there are compilation errors on RHEL10: redefinition of: 'struct flock', 'struct flock64', and 'struct f_owner_ex'
The same test case compiles successfully on RHEL-9.5 with kernel 5.14.0-480.el9. and gcc version 11.4.1 20231218.
Please provide the package NVR for which bug is seen:
- uname -r
6.10.0-15.el10.x86_64
Every time.
Steps to reproduce
I cut down test case to just a few lines and tried to run 'gcc -o test test.c'
#define _GNU_SOURCE
#include <linux/watch_queue.h>
#include <sys/mount.h>
int main()
{ return 0; }Expected results
Successful compilation
Actual results
