Subject: [PATCH] LOCKDEP: use depends on LOCKDEP_SUPPORT instead of $ARCH list
Date: Sun, 16 May 2021 20:44:30 -0700 [thread overview]
Message-ID: <20210517034430.9569-1-rdunlap@infradead.org> (raw)
Both arch/um/ and arch/xtensa/ cause a Kconfig warning for LOCKDEP.
These arch-es select LOCKDEP_SUPPORT but they are not listed as one
of the arch-es that LOCKDEP depends on.
Since (16) arch-es define the Kconfig symbol LOCKDEP_SUPPORT if they
intend to have LOCKDEP support, replace the awkward list of
arch-es that LOCKDEP depends on with the LOCKDEP_SUPPORT symbol.
Fixes this kconfig warning: (for both um and xtensa)
WARNING: unmet direct dependencies detected for LOCKDEP
Depends on [n]: DEBUG_KERNEL [=y] && LOCK_DEBUGGING_SUPPORT [=y] && (FRAME_POINTER [=n] || MIPS || PPC || S390 || MICROBLAZE || ARM || ARC || X86)
Selected by [y]:
- PROVE_LOCKING [=y] && DEBUG_KERNEL [=y] && LOCK_DEBUGGING_SUPPORT [=y]
- LOCK_STAT [=y] && DEBUG_KERNEL [=y] && LOCK_DEBUGGING_SUPPORT [=y]
- DEBUG_LOCK_ALLOC [=y] && DEBUG_KERNEL [=y] && LOCK_DEBUGGING_SUPPORT [=y]
