Subject: [PATCH 09/10] fs: allocate FILE table dynamically
Date: Sat, 9 Mar 2013 11:53:10 +0100 [thread overview]
Message-ID: <1362826391-16215-10-git-send-email-s.hauer@pengutronix.de> (raw)
In-Reply-To: <1362826391-16215-1-git-send-email-s.hauer@pengutronix.de>
Some systems are runnignfrom a very limited SRAM, but have a huge
malloc space in SDRAM. The bss normally is in SRAM, so we should
avoid having big structures there. The FILE table is 5120 bytes
big, so allocate it dynamically instead.
