Pull vfs fixes from Christian Brauner:
- netfs:
- Fix an uninitialized return value in netfs_unbuffered_write()
when preparing the first subrequest fails
- For partial unbuffered/DIO writes return the amount transferred
rather than an error
- Update i_size with the amount actually written when a partial
transfer ends in an error
- Fix a subrequest reference leak when the io_iter ends up empty
- Handle netfs_alloc_subrequest() failure during unbuffered writes
- Load all readahead folios into the rolling buffer upfront and
drop the readahead references once the first subrequest is
dispatched
- Mark folios for copy-to-cache while issuing subrequests
- Fix read progress reporting
- afs:
- Add the missing kunmap in the error path of afs_dir_search_bucket()
- Fix a double kunmap in afs_edit_dir_remove()
- Don't free an existing server's endpoint state when cleaning up a
candidate server in afs_lookup_server()
- Unbind peers removed from a server's address list
- ufs:
- Load the cylinder group metadata before creating the root dentry
- Validate the cylinder group index and rotor positions before
caching them
- Treat an unreadable directory block as not empty
- exec:
- Close the close-on-exec files before taking exec_update_lock
Closing a file can block on the filesystem, so a hung filesystem
blocked everything that takes exec_update_lock and a FUSE server
inspecting the calling process could deadlock
- Drop the bprm loader before closing bprm->file in free_bprm()
- exit: Hold a reference to thread_pid across proc_flush_pid()
- reboot: Fix a use-after-free on cad_pid
- nsfs: Keep the namespace tree fields out of the rcu_head used by
kfree_rcu()
- nstree: Check listing permission before taking a namespace
reference in listns()
- super: Return 0 when a nested thaw drops its hold while other
freezers remain
- ext4: Don't set I_METADATA_WRITEBACK during fastcommit replay
- adfs: Free s_fs_info in ->kill_sb()
- autofs: Free the inode info allocated in autofs_fill_super() when
the root inode allocation fails
- ovl: Return EINVAL instead of EIO on a user namespace mismatch now
that it's a plain refusal and not an internal error
- cachefiles: Don't cast the variable-length coherency data to a
__be64 in the coherency tracepoint
