entry error handling, allocation cleanup, FITRIM bounds, and locking:
- Fix valid_size extension over shared writable mappings by lazily
zeroing page-cache gaps and ensuring racing stores cannot be
overwritten or extend beyond valid_size.
- Clean up partially written directory entries on add-entry failure and
safely free new directory clusters.
- Free a newly allocated directory cluster when zeroing it fails.
- Write the destination entry before removing the source entry during
rename, preserving the source if the destination write fails.
- Keep FITRIM within the requested range, even when the free-space search
wraps around the allocation bitmap.
- Fix truncated FS_IOC_GETFSLABEL results by passing the destination
buffer size in bytes to the UTF-16-to-NLS conversion.
- Fix overflow in the cluster-to-dentry calculation, which could cause
readdir to stop early on large volumes.
- Replace the per-inode truncate_lock with inode_lock, using shared
locking in bmap to serialize against concurrent truncation.
- Update the exfat mailing list address in MAINTAINERS.
