Pull vfs fixes from Christian Brauner:
- Fix netfs_limit_iter() hitting BUG() when an ITER_KVEC iterator
reaches it via core dump writes to 9P filesystems. Add ITER_KVEC
handling following the same pattern as the existing ITER_BVEC code.
- Fix a NULL pointer dereference in the netfs unbuffered write retry
path when the filesystem (e.g., 9P) doesn't set the prepare_write
operation.
- Clear I_DIRTY_TIME in sync_lazytime for filesystems implementing
->sync_lazytime. Without this the flag stays set and may cause
additional unnecessary calls during inode deactivation.
- Increase tmpfs size in mount_setattr selftests. A recent commit
bumped the ext4 image size to 2 GB but didn't adjust the tmpfs
backing store, so mkfs.ext4 fails with ENOSPC writing metadata.
- Fix an invalid folio access in iomap when i_blkbits matches the folio
size but differs from the I/O granularity. The cur_folio pointer
would not get invalidated and iomap_read_end() would still be called
on it despite the IO helper owning it.
- Fix hash_name() docstring.
- Fix read abandonment during netfs retry where the subreq variable
used for abandonment could be uninitialized on the first pass or
point to a deleted subrequest on later passes.
- Don't block sync for filesystems with no data integrity guarantees.
Add a SB_I_NO_DATA_INTEGRITY superblock flag replacing the per-inode
AS_NO_DATA_INTEGRITY mapping flag so sync kicks off writeback but
doesn't wait for flusher threads. This fixes a suspend-to-RAM hang on
fuse-overlayfs where the flusher thread blocks when the fuse daemon
is frozen.
- Fix a lockdep splat in iomap when reads fail. iomap_read_end_io()
invokes fserror_report() which calls igrab() taking i_lock in hardirq
context while i_lock is normally held with interrupts enabled. Kick
failed read handling to a workqueue.
- Remove the redundant netfs_io_stream::front member and use
stream->subrequests.next instead, fixing a potential issue in the
direct write code path.
