From 33818bbb84cd371b63ed8849cc5264d24c8b3aa2 Mon Sep 17 00:00:00 2001 From: Artem Bityutskiy Date: Tue, 28 Aug 2007 21:29:32 +0300 Subject: UBI: allocate memory with GFP_NOFS Use GFP_NOFS flag when allocating memory on I/O path, because otherwise we may deadlock the filesystem which works on top of us. We observed the deadlocks with UBIFS. Example: VFS->FS lock a lock->UBI->kmalloc()->VFS writeback->FS locks the same lock again.
