-Introduce an (effectively) non-repeating system-unique superblock ID that
-can be used to determine that two objects are in the same superblock
-without needing to worry about the ID changing in the meantime (as is

-Subject: [PATCH 2/3] fsinfo: Add fsinfo() syscall to query filesystem
- information
-
-Add a system call to allow filesystem information to be queried.  A request
-value can be given to indicate the desired attribute.  Support is provided
-for enumerating multi-value attributes.
-
-===============
-NEW SYSTEM CALL
-===============
-
-The new system call looks like:
-
-	int ret = fsinfo(int dfd,
-			 const char *pathname,
-			 const struct fsinfo_params *params,
-			 size_t params_size,
-			 void *result_buffer,
-			 size_t result_buf_size);
-
-The params parameter optionally points to a block of parameters:
-
-	struct fsinfo_params {
-		__u64	resolve_flags;
-		__u32	at_flags;
-		__u32	flags;
-		__u32	request;
-		__u32	Nth;
-		__u32	Mth;
-	};
-
-If params is NULL, the default is that params->request is
-FSINFO_ATTR_STATFS and all the other fields are 0.  params_size indicates
-the size of the parameter struct.  If the parameter block is short compared
-to what the kernel expects, the missing length will be set to 0; if the
-parameter block is longer, an error will be given if the excess is not all
-zeros.
-
-The object to be queried is specified as follows - part param->flags
-indicates the type of reference:
-
- (1) FSINFO_FLAGS_QUERY_PATH - dfd, pathname and at_flags indicate a
-     filesystem object to query.
-
-     There is no separate system call providing an analogue of lstat() -
-     AT_SYMLINK_NOFOLLOW should be set in at_flags instead.
-     AT_NO_AUTOMOUNT can also be used to an allow automount point to be
-     queried without triggering it.
-
-     RESOLVE_* flags can also be set in resolve_flags to further restrict
-     the patchwalk.
-
- (2) FSINFO_FLAGS_QUERY_FD - dfd indicates a file descriptor pointing to
-     the filesystem object to query.  pathname should be NULL.
-
- (3) FSINFO_FLAGS_QUERY_MOUNT - pathname indicates the numeric ID of the
-     mountpoint to query as a string.  dfd is used to constrain which
-     mounts can be accessed.  If dfd is AT_FDCWD, the mount must be within
-     the subtree rooted at chroot, otherwise the mount must be within the
-     subtree rooted at the directory specified by dfd.
-
- (4) In the future FSINFO_FLAGS_QUERY_FSCONTEXT will be added - dfd will
-     indicate a context handle fd obtained from fsopen() or fspick(),
-     allowing that to be queried before the target superblock is attached
-     to the filesystem or even created.
-
-params->request indicates the attribute/attributes to be queried.  This can
-be one of:
-
-	FSINFO_ATTR_STATFS		- statfs-style info
-	FSINFO_ATTR_IDS			- Filesystem IDs
-	FSINFO_ATTR_LIMITS		- Filesystem limits
-	FSINFO_ATTR_SUPPORTS		- Support for statx, ioctl, etc.
-	FSINFO_ATTR_TIMESTAMP_INFO	- Inode timestamp info
-	FSINFO_ATTR_VOLUME_ID		- Volume ID (string)
-	FSINFO_ATTR_VOLUME_UUID		- Volume UUID
-	FSINFO_ATTR_VOLUME_NAME		- Volume name (string)
-	FSINFO_ATTR_FSINFO_ATTRIBUTE_INFO - Information about attr Nth
-	FSINFO_ATTR_FSINFO_ATTRIBUTES	- List of supported attrs
-
-Some attributes (such as the servers backing a network filesystem) can have
-multiple values.  These can be enumerated by setting params->Nth and
-params->Mth to 0, 1, ... until ENODATA is returned.
-
-result_buffer and result_buf_size point to the reply buffer.  The buffer is
-filled up to the specified size, even if this means truncating the reply.
-The size of the full reply is returned, irrespective of the amount data
-that was copied.  In future versions, this will allow extra fields to be
-tacked on to the end of the reply, but anyone not expecting them will only
-get the subset they're expecting.  If either buffer of result_buf_size are
-0, no copy will take place and the data size will be returned.

-Date: Tue, 3 Mar 2020 14:29:27 +0000
-Subject: [PATCH 3/3] fsinfo: Allow retrieval of superblock devname, options
- and stats
-
-Provide fsinfo() attributes to retrieve superblock device name, options,
-and statistics in string form.  The following attributes are defined:
-
-	FSINFO_ATTR_SOURCE		- Mount-specific device name
-	FSINFO_ATTR_CONFIGURATION	- Mount options
-	FSINFO_ATTR_FS_STATISTICS	- Filesystem statistics
-
-FSINFO_ATTR_SOURCE could be made indexable by params->Nth to handle the
-case where there is more than one source (e.g. the bcachefs filesystem).
-
-Signed-off-by: David Howells <dhowells@redhat.com>
