After adding probes, perf-probe(1) reports the probes locations which include
filenames for certain cases.
But for short file names (whose length < 32), perf-probe didn't display the
name correctly. It actually skipped the first character.
Here's an example where 'icmp.c' was screwed:
$ perf probe -n -a "icmp.c;sk=*"
Add new events:
probe:icmp_push_reply (on @cmp.c)
probe:icmp_reply (on @cmp.c)
probe:icmp_reply_1 (on @cmp.c)
probe:icmp_send (on @cmp.c)
probe:icmp_send_1 (on @cmp.c)
probe:icmp_error (on @cmp.c)
probe:icmp_error_1 (on @cmp.c)
probe:icmp_error_2 (on @cmp.c)
probe:icmp_error_3 (on @cmp.c)
This patch fixes this bug in synthesize_perf_probe_point().
