Date: Fri, 17 Nov 2023 23:52:17 +0000 From: bugzilla-daemon@...nel.org To: linux-ext4@...r.kernel.org Subject: [Bug 217965] ext4(?) regression since 6.5.0 on sata hdd https://bugzilla.kernel.org/show_bug.cgi?id=217965 --- Comment #37 from Eyal Lebedinsky (bugzilla@...l.emu.id.au) --- Finally got it. kernel 6.5 was easy. kernel-6.4 debuginfo could not be found with 'dnf' and I searched long for it. 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 = mb_find_extent(e4b, i, sbi->s_stripe, &ex); 24 if (max >= sbi->s_stripe) { 25 ac->ac_found++; 26 ex.fe_logical = 0xDEADF00D; /* debug value */ ac->ac_b_ex = ex; 28 ext4_mb_use_best_found(ac, e4b); 29 break; } } 32 i += sbi->s_stripe; } and decided to pick line 24 (not the original 26). Is this right? I will now upload the reports. -- You may reply to this email to add a comment. You are receiving this mail because: You are watching the assignee of the bug.
