2019-01-08tools include uapi: Grab a copy of linux/mount.hArnaldo Carvalho de Melo1-0/+58
We were using a copy of uapi/linux/fs.h to create the mount syscall 'flags' string table to use in 'perf trace', to convert from the number obtained via the raw_syscalls:sys_enter into a string, using tools/perf/trace/beauty/mount_flags.sh, but in e262e32d6bde ("vfs: Suppress MS_* flag defs within the kernel unless explicitly enabled") those defines got moved to linux/mount.h, so grab a copy of mount.h too. Keep the uapi/linux/fs.h as we'll use it for the SEEK_ constants.
