mm: replace PF_KCOMPACTD flag with kthread_func() check

2026-09-14T04:32:02+00:00

PF_KCOMPACTD was introduced by commit ce6d9c1c2b5c ("NFS: fix nfs_release_folio() to not deadlock via kcompactd writeback") so nfs_release_folio() could detect kcompactd context and skip writeback. The flag is only consumed by current_is_kcompactd(), whose sole caller is nfs_release_folio(). Replace the flag-based check with kthread_func(current) == kcompactd, freeing the 0x00010000 PF flag bit.

mm: replace PF_KSWAPD flag with kthread_func() check

2026-09-14T04:32:01+00:00

The preceding commits removed the last consumer that propagated PF_KSWAPD beyond kswapd itself (XFS btree split worker inheritance). The only remaining setter of PF_KSWAPD is kswapd(), and every current_is_kswapd() caller only needs to check whether the current task *is* the kswapd thread, not whether it inherited the flag. Replace the flag-based test with kthread_func(current) == kswapd, freeing the 0x00020000 PF flag bit.

tools/sched_ext: Drop the no-op -rdynamic from CFLAGS

2026-09-08T17:01:42+00:00

Because CFLAGS only applies to compilation ($(CC) -c), the link-time flag -rdynamic is inert during the build. Schedulers do not rely on exported dynamic symbols, and binaries remain byte-identical without it. Under -Werror, Clang treats this unused argument as a build error: $ make CC=clang-21 clang-21: error: argument unused during compilation: '-rdynamic' [-Werror,-Wunused-command-line-argument] Drop -rdynamic from CFLAGS to ensure clean builds across Clang versions.

sched_ext: scx_qmap: Fix pending partition work handoff

2026-09-06T22:39:15+00:00

qmap can leave partition work pending with no runner. The effective-cap callback publishes its request after failing to acquire part_busy, while redistribute() checks for pending work before releasing it. Either ordering can miss a request arriving as the current runner finishes, delaying the update until the round-robin timer runs. Publish requests before trying to become the runner and release part_busy before checking for more work. Have all holders drain pending requests after releasing it, including the stats flush. Distinguish mask refreshes from repartitions so an effective-cap update only rebuilds the partition when a repartition was also requested.
