Motivation and Context

Elsewhere, the intptr_t is defined as a signed int type, but it was defined as unsigned here. This was found to be breaking the build for me against 5.9rc1.

Description

Change the definition of intptr_t from unsigned long to long

How Has This Been Tested?

Tested build against 6.4.2, and tested against 6.5rc1 (however, 6.5rc1 has other breaking changes too).

Types of changes

  • Bug fix (non-breaking change which fixes an issue)
  • New feature (non-breaking change which adds functionality)
  • Performance enhancement (non-breaking change which improves efficiency)
  • Code cleanup (non-breaking change which makes code smaller or more readable)
  • Breaking change (fix or feature that would cause existing functionality to change)
  • Library ABI change (libzfs, libzfs_core, libnvpair, libuutil and libzfsbootenv)
  • Documentation (a change to man pages or other documentation)

Checklist:

@ckane
intptr_t definition is canonically signed

Make the version here match that elsewhere in the kernel and system
headers.

Right. intptr_t should be signed, unlike uintptr_t. I am just curios, why intptr_t is declared here, while uintptr_t is not. How does it work?
