prlimit: add name redirection and fix incorrect parameters to syscall
The tst-rlimit/tst-rlimit64 tests pointed to several issueses in prlimit() function for 32-bit CPUs. This patch adds name redirection to prlimit64 in prlimit declaration to provide correct support for 64-bit offset (_FILE_OFFSET_BITS=64) on 32-bit CPUs and fixes improper field assignment and incorrect syscall paramerets in the prlimit() function. Fixes: 8c2f6218 ("setrlimit/getrlimit: fix prlimit64 syscall use for 32-bit CPUs") Signed-off-by: Pavel Kozlov <pavel.kozlov@synopsys.com>
