/* Summary */
This contains fixes for this merge window:
VFS:
- Ensure that backing files uses file->f_ops->splice_write() for splice.
netfs:
- Revert the removal of PG_private_2 from netfs_release_folio() as cephfs still
relies on this.
- When AS_RELEASE_ALWAYS is set on a mapping the folio needs to always be
invalidated during truncation.
- Fix losing untruncated data in a folio by making letting
netfs_release_folio() return false if the folio is dirty.
- Fix trimming of streaming-write folios in netfs_inval_folio() .
- Reset iterator before retrying a short read.
- Fix interaction of streaming writes with zero-point tracker
afs:
- During truncation afs currently calls truncate_setsize() which sets i_size,
expands the pagecache and truncates it. The first two operations aren't
needed because they will have already been done. So call truncate_pagecache()
instead and skip the redundant parts.
overlayfs:
- Fix checking of the number of allowed lower layers so 500 layers can actually
be used instead of just 499
- Add missing '\n' to pr_err() output.
- Pass string to ovl_parse_layer() and thus allow it to be used for
Opt_lowerdir as well.
pidfd:
- Revert blocking the creation of pidfds for kthread as apparently userspace
relies on this. Specifically, it breaks systemd during shutdown.
romfs:
- Fix romfs_read_folio() to use the correct offset with folio_zero_tail().
