Subject: Query about cyclic buffer size
Date: Thu, 13 Sep 2012 10:10:18 -0400	[thread overview]
Message-ID: <20120913141018.GG4396@redhat.com> (raw)

Hi Atsushi-san,

How is size of cyclic buffer decided with 1.5.0? In practice I don't think
asking user for the size is a good idea as user does not know how much
memory will be left after kernel boot.

Will it make sense for makedumpfile to automatically determine the buffer
size based on amount of free memory available in the system. Something
like use 70-80% of free memory as cyclic buffer.

Thanks
Vivek
