[GIT PULL 02/16 for v7.2] vfs exportfs

[Christian Brauner]

Hey Linus,

/* Summary */

This cleans up the exportfs support for block-style layouts that
provide direct block device access: the operations for layout-based
block device access are split out of struct export_operations into a
separate header, ->commit_blocks() no longer takes a struct iattr
argument, and the way support for layout-based block device access is
detected is reworked. nfsd's blocklayout code also stops honoring
loca_time_modify. This is preparation for supporting export of more
than a single device per file system.

Note that the nfsd tree is based on a merge of this branch so these
changes may also reach you through the nfsd pull request.

/* Testing */

gcc (Debian 14.2.0-19) 14.2.0
Debian clang version 19.1.7 (3+b1)

No build failures or warnings were observed.
