replace_fd() returns the number of the new file descriptor through the
return value of do_dup2(). However its callers never care about the
specific returned number. In fact the caller in receive_fd_replace() treats
any non-zero return value as an error and therefore never calls
__receive_sock() for most file descriptors, which is a bug.
To fix the bug in receive_fd_replace() and to avoid the same issue
happening in future callers, signal success through a plain zero.

With fuse now using iomap for writeback handling, inode blkbits changes
are problematic because iomap relies on inode->i_blkbits for its
internal bitmap logic. Currently we change inode->i_blkbits in fuse to
match the attr->blksize value passed in by the server.
This commit keeps inode->i_blkbits constant in fuse. Any attr->blksize
values passed in by the server will not update inode->i_blkbits. The
client-side behavior for stat is unaffected, stat will still reflect the
blocksize passed in by the server.

Commit d279c80e0b ("iomap: inline iomap_dio_bio_opflags()") has broken
the logic in iomap_dio_bio_iter() in a way that when the device does
support FUA (or has no writeback cache) and the direct IO happens to
freshly allocated or unwritten extents, we will *not* issue fsync after
completing direct IO O_SYNC / O_DSYNC write because the
IOMAP_DIO_WRITE_THROUGH flag stays mistakenly set. Fix the problem by
clearing IOMAP_DIO_WRITE_THROUGH whenever we do not perform FUA write as
it was originally intended.

Atomic writes are not currently supported for DAX, but two problems exist:
- we may go down DAX write path for IOCB_ATOMIC, which does not handle
IOCB_ATOMIC properly
- we report non-zero atomic write limits in statx (for DAX inodes)
We may want atomic writes support on DAX in future, but just disallow for
now.
For this, ensure when IOCB_ATOMIC is set that we check the write size
versus the atomic write min and max before branching off to the DAX write
path. This is not strictly required for DAX, as we should not get this far
in the write path as FMODE_CAN_ATOMIC_WRITE should not be set.
In addition, due to reflink being supported for DAX, we automatically get
CoW-based atomic writes support being advertised. Remedy this by
disallowing atomic writes for a DAX inode for both sw and hw modes.

This patch adds firmware loading and parsing support for FourSemi audio
amplifiers. The library handles firmware file (*.bin) generated by the
FourSemi tuning tool, which contains:
- Register initialization settings
- DSP effect parameters
- Multi-scene sound effect switching configurations(optional)
The firmware is required for proper initialization and configuration
of FourSemi amplifier devices.
