Subject: [PATCH] Get rid of __syscall_count.
Date: Tue, 01 Jul 2003 15:36:25 +1000 [thread overview]
Message-ID: <20030701054635.A2D532C0B1@lists.samba.org> (raw)
Linus, please apply, unless someone has plans for this field.
Noone seems to use __syscall_count. Remove the field from i386
irq_cpustat_t struct, and the generic accessor macros.
Because some archs have hardcoded asm references to offsets in this
structure, I haven't touched non-x86, but doing so is usually
trivial.
