[PATCH 14/23] tools headers uapi: Sync linux/fscrypt.h with the kernel sources

[Arnaldo Carvalho de Melo]

From: Arnaldo Carvalho de Melo <acme@xxxxxxxxxx>

To pick the changes from:

  e933adde6f97 ("fscrypt: include <linux/ioctl.h> in UAPI header")
  93edd392cad7 ("fscrypt: support passing a keyring key to FS_IOC_ADD_ENCRYPTION_KEY")

That don't trigger any changes in tooling.

This silences this perf build warning:

  Warning: Kernel ABI header at 'tools/include/uapi/linux/fscrypt.h' differs from latest version at 'include/uapi/linux/fscrypt.h'
