[Cluster-devel] [PATCH/RFC dlm/next 0/9] fs: dlm: change lock and endianness handling

[Alexander Aring <aahringo@redhat.com>]

Hi,

this patch series removes all sparse warnings which are occur when
calling:

make C=2 fs/dlm/*.o

This patch series will not fix anything, but changes e.g. the endianness
handling in dlm so we probably can find issues in future if dlm wire
message value is compared against a host byte order value.

Otherwise there are some changes regarding casting or move functions
around to make sparse quiet that it does not complain about those
sections which are in my opinion false positives or at least handle it
in such way right now to find a better solution in future.

I hope I caught all necessary endianness conversions (sparse does not
complain if a format string and a value is handled as non host byte
order for printout, but I tried to caught them all). There might be some
better options to handle e.g. lkb types directly in little endian as it is
dlm wire byte order. However this patch series will at first remove the
in/out functionality for byte order conversion. There might be in future
more follow up patches to change the byte order conversion in dlm
application stack.
