svn commit: r349750 - head/sys/compat/linux

[Edward Tomasz Napierala]

Author: trasz
Date: Thu Jul  4 20:16:04 2019
New Revision: 349750
URL: https://svnweb.freebsd.org/changeset/base/349750

Log:
  Return ENOTSUP for Linux FS_IOC_FIEMAP ioctl.
  
  Linux man(1) calls it for no good reason; this avoids the console spam
  (eg '(man): ioctl fd=4, cmd=0x660b ('f',11) is not implemented').
