List-Id: Linux MTD discussion mailing list List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Hi there, IIUC than mounting a JFFS2 root fs takes so long (6 seconds on my embedded ARM9) cause the CRCs of all blocks/sectors are checked. But then it looks to me that - shortly after boot - the GC thread doing the same again (in background.c), which takes another 6 scondes and slows down the application startup... Or am I missing something? -- Steven Scholz imc Measurement & Control
