NTB: ntb_tool: reading the link file should not end in a NULL byte [ Upstream commit 912e12813dd03c602e4922fc34709ec4d4380cf0 ] When running ntb_test this warning is issued: ./ntb_test.sh: line 200: warning: command substitution: ignored null byte in input This is caused by the kernel returning one more byte than is necessary when reading the link file. Reduce the number of bytes read back to 2 as it was before the commit that regressed this.
