Description

Trying to build patchless client for SLES 10 x64.

Build fails with error:

/storage/asl/sles10/workdir/BUILD/lustre-2.0.66/lustre/llite/llite_nfs.c:244: warning: passing argument 3 of 'll_readdir'.

Why are you trying to build 2.0.66? What is the prototype for filldir_t on SLES10? What specific kernel version is being used?

[Cheng Shao (Inactive)]

Sorry about the confusion. The problem exists with the latest Lustre version as well.

There are a couple of issues when compiling lustre with old kernel versions. Specifically,

• For 2.6.18 and earlier, filldir_t is defined as below, with fourth argument type of ino_t,
  typedef int (*filldir_t)(void *, const char *, int, loff_t, ino_t, unsigned);
  It was changed to u64 in later kernel versions.

• For 2.6.17 and earlier, address_space_operations->migratepage() takes two args instead of three

• For 2.6.18 and earlier, there is no bool type.

We have the above issue fixed in our repo and will get it landed on WC via this ticket.

Note that SLES10 clients are not supported for master
