Regression; drive on a removable usb device does not mount

Performance - NTFS vs WinBtrfs

Constant Freezes

Kernel pool buffer overflow when setting extended attributes (uint16 size wraparound)

Deadlock: flush_thread vs Cc write-behind on sustained heavy writes (v1.10, #345 family still present)

The correct way to run upgrade the driver (and to switch between the debug and release builds)

v1.10 goes into BSOD on file removal, writing, even on idling: `SYSTEM_THREAD_EXCEPTION_NOT_HANDLED`

Support for deduplication

send: WRITE offsets wrong for extents with nonzero extent offset (silent corruption on receive); OOB reads; unchecked buffer growth; uint16 path wraparound

Uninitialized variables and lifetime bugs: mknod (inode/subvol), mount_vol failure after VPB_MOUNTED, create_calc_threads typo, delayed notifications, balance chunk pointer

Trusted length fields: set_label reads past the input buffer (kernel info leak); rename/link trust FileNameLength

drv_query_volume_information: most branches write fixed-size structs without checking the output buffer length (pool overflow)

Buffer overflows from uint16 truncation in symlink reparse handling (get_reparse_block / get_reparse_point)

Reference/memory leaks on common paths: same-directory rename, hard-link query, create_subvol, etc.

scrub: RAID10 repair writes to wrong device offsets (data corruption); devices[j+j] typo; RAID56 MDL double free; stale rewrite flag
