tools include UAPI: Update linux/mount.h copy

tools include UAPI: Update copy of files related to new fspick, fsmount, fsconfig, fsopen, move_mount and open_tree syscalls

2019-05-28T12:49:03Z

Copy the headers changed by these csets: d8076bdb56af ("uapi: Wire up the mount API syscalls on non-x86 arches [ver #2]") 9c8ad7a2ff0b ("uapi, x86: Fix the syscall numbering of the mount API syscalls [ver #2]") cf3cba4a429b ("vfs: syscall: Add fspick() to select a superblock for reconfiguration") 93766fbd2696 ("vfs: syscall: Add fsmount() to create a mount for a superblock") ecdab150fddb ("vfs: syscall: Add fsconfig() for configuring and managing a context") 24dcb3d90a1f ("vfs: syscall: Add fsopen() to prepare for superblock creation") 2db154b3ea8e ("vfs: syscall: Add move_mount(2) to move mounts around") a07b20004793 ("vfs: syscall: Add open_tree(2) to reference or clone a mount") We need to create tables for all the flags argument in the new syscalls, in followup patches.

tools include uapi: Grab a copy of linux/mount.h

2019-01-08T17:09:28Z

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.
