[LTP] [PATCH] pkeys: Fix uclibc build caused by conflicting signature

[Petr Vorel]

Removing static fixes the problem.

uClibc defines pkey_{alloc,free,mprotect} signatures in
<bits/mman-shared.h>, which is included by <bits/mman-linux.h>.  Because
it does not implement them, our implementation signature conflicts, as
it uses static.

Fixed build error:
In file included from pkey01.c:32:0:
pkey.h:18:19: error: static declaration of ‘pkey_mprotect’ follows non-static declaration
 static inline int pkey_mprotect(void *addr, size_t len, int prot, int pkey)

Found with test-pkg tool from Buildroot distribution.
