Message-ID: <20111011091340.4881.qmail@sourceware.org> (raw)
CVSROOT: /cvs/lvm2
Module name: LVM2
Changes by: zkabelac at sourceware.org 2011-10-11 09:13:39
Modified files:
doc : example.conf.in
lib/config : defaults.h
Log message:
Reduce preallocated stack size
Go with just 64KiB for stack.
Closer inspection should be made, whether we actually need to play with
settings at all.
Since default stack size is 8MB and gets mapped via page locking thus,
it seems there is no big help with preallocation of stack to some value.
