From 6c29046439b78e2593213f30656fa85f0ff2ce77 Mon Sep 17 00:00:00 2001 From: mmacy Date: Sat, 27 Jun 2020 00:57:48 +0000 Subject: [PATCH] Fix "current" variable name conflict with openzfs The variable "current" is an alias for curthread in openzfs. Rename all variable uses of current in dtrace.c to curstate. --- .../opensolaris/uts/common/dtrace/dtrace.c | 78 +++++++++---------- 1 file changed, 39 insertions(+), 39 deletions(-) diff --git a/sys/cddl/contrib/opensolaris/uts/common/dtrace/dtrace.c b/sys/cddl/contrib/opensolaris/uts/common/dtrace/dtrace.c index cab8c334d082..8399be770bb0 100644 --- a/sys/cddl/contrib/opensolaris/uts/common/dtrace/dtrace.c +++ b/sys/cddl/contrib/opensolaris/uts/common/dtrace/dtrace.c @@ -2780,25 +2780,25 @@ static int dtrace_speculation(dtrace_state_t *state) { int i = 0; - dtrace_speculation_state_t current; + dtrace_speculation_state_t curstate; uint32_t *stat = &state->dts_speculations_unavail, count; while (i < state->dts_nspeculations) { dtrace_speculation_t *spec = &state->dts_speculations[i]; - current = spec->dtsp_state; + curstate = spec->dtsp_state; - if (current != DTRACESPEC_INACTIVE) { - if (current == DTRACESPEC_COMMITTINGMANY || - current == DTRACESPEC_COMMITTING || - current == DTRACESPEC_DISCARDING) + if (curstate != DTRACESPEC_INACTIVE) { + if (curstate == DTRACESPEC_COMMITTINGMANY || + curstate == DTRACESPEC_COMMITTING || + curstate == DTRACESPEC_DISCARDING) stat = &state->dts_speculations_busy; i++; continue; } if (dtrace_cas32((uint32_t *)&spec->dtsp_state, - current, DTRACESPEC_ACTIVE) == current) + curstate, DTRACESPEC_ACTIVE) == curstate) return (i + 1); } @@ -2827,7 +2827,7 @@ dtrace_speculation_commit(dtrace_state_t *state, processorid_t cpu, dtrace_speculation_t *spec; dtrace_buffer_t *src, *dest; uintptr_t daddr, saddr, dlimit, slimit; - dtrace_speculation_state_t current, new = 0; + dtrace_speculation_state_t curstate, new = 0; intptr_t offs; uint64_t timestamp; @@ -2844,12 +2844,12 @@ dtrace_speculation_commit(dtrace_state_t *state, processorid_t cpu, dest = &state->dts_buffer[cpu]; do { - current = spec->dtsp_state; + curstate = spec->dtsp_state; - if (current == DTRACESPEC_COMMITTINGMANY) + if (curstate == DTRACESPEC_COMMITTINGMANY) break; - switch (current) { + switch (curstate) { case DTRACESPEC_INACTIVE: case DTRACESPEC_DISCARDING: return; @@ -2891,7 +2891,7 @@ dtrace_speculation_commit(dtrace_state_t *state, processorid_t cpu, ASSERT(0); } } while (dtrace_cas32((uint32_t *)&spec->dtsp_state, - current, new) != current); + curstate, new) != curstate); /* * We have set the state to indicate that we are committing this @@ -2907,7 +2907,7 @@ dtrace_speculation_commit(dtrace_state_t *state, processorid_t cpu, /* * We have sufficient space to copy the speculative buffer into the * primary buffer.
