Finally locating it on koji. Then the third probe was wrong, and after some learning I discovered $ sudo perf probe --line "ext4_mb_scan_aligned" 21 while (i < EXT4_CLUSTERS_PER_GROUP(sb)) { 22 if (!mb_test_bit(i, bitmap)) { 23 max =3D mb_find_extent(e4b, i, sbi->s_strip= e, &ex); 24 if (max >=3D sbi->s_stripe) { 25 ac->ac_found++; 26 ex.fe_logical =3D 0xDEADF00D; /* de= bug value */ ac->ac_b_ex =3D ex; 28 ext4_mb_use_best_found(ac, e4b); 29 break; } } 32 i +=3D sbi->s_stripe; } and decided to pick line 24 (not the original 26). Is this right? I will now upload the reports. --=20 You may reply to this email to add a comment. You are receiving this mail because: You are watching the assignee of the bug.=
