Regarding linux kernel commit 805e3ce5e0e32b31dcecc0774c57c17a1f13cef6

by Srinivasa Srikanth Podila

Hello, I have come across the linux kernel commit 805e3ce5e0e32b31dcecc0774c57c17a1f13cef6 merged into the 6.15 kernel. Kernel Commit: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… Currently, we need this fix into the latest 6.8 based kernel as our servers are all based on Ubuntu 24.04 with 6.8 based kernels. Please let us know the process for the same. Could you please help in this regard. Any help on this would be greatly appreciated. Thanks, Srikanth

[PATCH 6.6] gfs2: replace sd_aspace with sd_inode

by Sumanth Gavini

commit ae9f3bd8259a0a8f67be2420e66bb05fbb95af48 upstream. Currently, sdp->sd_aspace and the per-inode metadata address spaces use sb->s_bdev->bd_mapping->host as their ->host; folios in those address spaces will thus appear to be on bdev rather than on gfs2 filesystems. This is a problem because gfs2 doesn't support cgroup writeback (SB_I_CGROUPWB), but bdev does. Fix that by using a "dummy" gfs2 inode as ->host in those address spaces. When coming from a folio, folio->mapping->host->i_sb will then be a gfs2 super block and the SB_I_CGROUPWB flag will not be set in sb->s_iflags. Based on a previous version from Bob Peterson from several years ago. Thanks to Tetsuo Handa, Jan Kara, and Rafael Aquini for helping figure this out.

[PATCH 6.6] io_uring/rw: ensure reissue path is correctly handled for IOPOLL

by Sumanth Gavini

commit bcb0fda3c2da9fe4721d3e73d80e778c038e7d27 upstream. The IOPOLL path posts CQEs when the io_kiocb is marked as completed, so it cannot rely on the usual retry that non-IOPOLL requests do for read/write requests. If -EAGAIN is received and the request should be retried, go through the normal completion path and let the normal flush logic catch it and reissue it, like what is done for !IOPOLL reads or writes. Fixes: d803d123948f ("io_uring/rw: handle -EAGAIN retry at IO completion time") Reported-by: John Garry <john.g.garry(a)oracle.com> Link: https://lore.kernel.org/io-uring/2b43ccfa-644d-4a09-8f8f-39ad71810f41@oracl… Signed-off-by: Jens Axboe <axboe(a)kernel.dk> Signed-off-by: Sumanth Gavini <sumanth.gavini(a)yahoo.com> --- io_uring/rw.c | 7 +++---- 1 file changed, 3 insertions(+), 4 deletions(-) diff --git a/io_uring/rw.c b/io_uring/rw.c index 4ff3442ac2ee..6a84c4a39ce9 100644 --- a/io_uring/rw.c +++ b/io_uring/rw.c @@ -326,11 +326,10 @@ static void io_complete_rw_iopoll(struct kiocb *kiocb, long res) if (kiocb->ki_flags & IOCB_WRITE) io_req_end_write(req); if (unlikely(res != req->cqe.res)) { - if (res == -EAGAIN && io_rw_should_reissue(req)) { + if (res == -EAGAIN && io_rw_should_reissue(req)) req->flags |= REQ_F_REISSUE | REQ_F_PARTIAL_IO; - return; - } - req->cqe.res = res; + else + req->cqe.res = res; } /* order with io_iopoll_complete() checking ->iopoll_completed */ -- 2.43.0

[PATCH 6.12 1/6] drm/i915/ddi: change intel_ddi_init_{dp, hdmi}_connector() return type

by Sergey Senozhatsky

From: Jani Nikula <jani.nikula(a)intel.com> [ Upstream commit e1980a977686d46dbf45687f7750f1c50d1d6cf8 ] The caller doesn't actually need the returned struct intel_connector; it's stored in the ->attached_connector of intel_dp and intel_hdmi. Switch to returning an int with 0 for success and negative errors codes to be able to indicate success even when we don't have a connector.

[PATCH v4 19/24] mtd: spinand: propagate spinand_wait() errors from spinand_write_page()

by Mikhail Kshevetskiy

From: Gabor Juhos <j4g8y7(a)gmail.com> Since commit 3d1f08b032dc ("mtd: spinand: Use the external ECC engine logic") the spinand_write_page() function ignores the errors returned by spinand_wait(). Change the code to propagate those up to the stack as it was done before the offending change.
