fs: spell out fenced ->i_state accesses with explicit smp_wmb/smp_rmb

2025-10-20T18:22:26+00:00

The incomming helpers don't ship with _release/_acquire variants, for the time being anyway. Signed-off-by: Mateusz Guzik Signed-off-by: Christian Brauner

mm: remove BDI_CAP_WRITEBACK_ACCT

2025-08-27T12:29:43+00:00

There are no users of BDI_CAP_WRITEBACK_ACCT now that fuse doesn't do its own writeback accounting. This commit removes BDI_CAP_WRITEBACK_ACCT. Signed-off-by: Joanne Koong Acked-by: David Hildenbrand Signed-off-by: Miklos Szeredi

fuse: use default writeback accounting

2025-08-27T12:29:43+00:00

commit 0c58a97f919c ("fuse: remove tmp folio for writebacks and internal rb tree") removed temp folios for dirty page writeback. Consequently, fuse can now use the default writeback accounting. With switching fuse to use default writeback accounting, there are some added benefits. This updates wb->writeback_inodes tracking as well now and updates writeback throughput estimates after writeback completion. This commit also removes inc_wb_stat() and dec_wb_stat(). These have no callers anymore now that fuse does not call them. Signed-off-by: Joanne Koong Reviewed-by: David Hildenbrand Reviewed-by: Bernd Schubert Signed-off-by: Miklos Szeredi

writeback: fix false warning in inode_to_wb()

2025-04-18T03:10:08+00:00

inode_to_wb() is used also for filesystems that don't support cgroup writeback. For these filesystems inode->i_wb is stable during the lifetime of the inode (it points to bdi->wb) and there's no need to hold locks protecting the inode->i_wb dereference. Improve the warning in inode_to_wb() to not trigger for these filesystems.

writeback: move wb_wakeup_delayed defination to fs-writeback.c

The wb_wakeup_delayed is only used in fs-writeback.c. Move it to fs-writeback.c after defination of wb_wakeup and make it static. Signed-off-by: Kemeng Shi Link: https://lore.kernel.org/r/20240118203339.764093-1-shikemeng@huaweicloud.com Reviewed-by: Jan Kara Signed-off-by: Christian Brauner

It seems it was introduced by commit d3f77dfdc718 ("blkcg: implement REQ_CGROUP_PUNT") unintentionally, but the definition does not exist, remove it.
