* [PATCH] f2fs: fix to freeze GC and discard threads quickly @ 2026-03-10 20:49 Daeho Jeong 2026-03-11 14:59 ` [f2fs-dev] " Chao Yu 0 siblings, 1 reply; 5+ messages in thread From: Daeho Jeong @ 2026-03-10 20:49 UTC (permalink / raw) To: linux-kernel, linux-f2fs-devel, kernel-team; +Cc: Daeho Jeong From: Daeho Jeong <daehojeong@google.com> Suspend can fail if kernel threads do not freeze for a while. f2fs_gc and f2fs_discard threads can perform long-running operations that prevent them from reaching a freeze point in a timely manner. This patch adds explicit freezing checks in the following locations: 1. f2fs_gc: Added a check at the 'retry' label to exit the loop quickly if freezing is requested, especially during heavy GC rounds. 2. __issue_discard_cmd: Added a 'suspended' flag to break both inner and outer loops during discard command issuance if freezing is detected after at least one command has been issued. 3. __issue_discard_cmd_orderly: Added a similar check for orderly discard to ensure responsiveness. These checks ensure that the threads release locks safely and enter the frozen state.

Otherwise, we can't meet the 1 second suspend requirement for Android. This logic mainly targets zufs proactive GC cases.

Sorry, I didn't get the point, could you please explain more about your concern? Actually, what I mean is if we missed freezeing() check condition in f2fs_gc(), in do_garbage_collection(), after we migrated one segment of section, and before migrate next segment in section, we can check freezing() condition at this time? I meant maybe we can add more check spots in do_garbage_collection().
