  erofs: error out obviously illegal extents in advance (2026-04-10 16:53:39 +0800)

----------------------------------------------------------------
Changes since last update:

 - Validate xattr h_shared_count to report -EFSCORRUPTED explicitly
   for crafted images

 - Verify metadata accesses for file-backed mounts via rw_verify_area()

 - Fix FS_IOC_GETFSLABEL to include the trailing NUL byte, consistent
   with ext4 and xfs

 - Properly handle 48-bit on-disk blocks/uniaddr for extra devices

 - Fix an index underflow in the LZ4 in-place decompression that can
   cause out-of-bounds accesses with crafted images

 - Minor fixes and cleanups
