[PATCH 0/2] Fix /proc/sys/fs/nfs/nsm_use_hostnames on big endian machines

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



There is an endianess problem with /proc/sys/fs/nfs/nsm_use_hostnames
(which can e.g. be seen on an s390x host) :

 # modprobe lockd nsm_use_hostnames=1
 # cat /proc/sys/fs/nfs/nsm_use_hostnames
 16777216

The nsm_use_hostnames variable is declared as "bool" which is required
for the correct type for the module parameter. However, this does not
work correctly with the entry in the /proc filesystem since this
currently requires "int".

Jia He already provided patches for this problem a couple of years ago,
but apparently they felt through the cracks and never got merged. So
here's a rebased version to finally fix this issue.

  sysctl: introduce new proc handler proc_dobool
  lockd: change the proc_handler for nsm_use_hostnames
