perf data: Support using -f to override perf.data file ownership for 'convert'
Enable perf data convert to use perf.data when it is not owned by
current user or root.
Example:
# perf record ls
# chown Yunlong.Song:Yunlong.Song perf.data
# ls -al perf.data
-rw------- 1 Yunlong.Song Yunlong.Song 28260 Apr 2 17:35 perf.data
# id
uid=0(root) gid=0(root) groups=0(root),64(pkcs11)
Before this patch:
# perf data convert --to-ctf=./ctf-data/
File perf.data not owned by current user or root (use -f to override)
# perf data convert --to-ctf=./ctf-data/ -f
Error: unknown switch `f'
usage: perf data convert [<options>]
-v, --verbose be more verbose
-i, --input <file> input file name
--to-ctf ... Convert to CTF format
After this patch:
# perf data convert --to-ctf=./ctf-data/
File perf.data not owned by current user or root (use -f to override)
# perf data convert --to-ctf=./ctf-data/ -f
# ls ctf-data/
metadata perf_stream_0
As shown above, the -f option really works now.
