Date: Wed, 17 Aug 2011 14:02:09 +0300 From: Surbhi Palande <ameyasurbhi@...il.com> To: linux-ext4@...r.kernel.org Cc: Jan Kara <jack@...e.cz>, Ted Tso <tytso@....edu> Subject: ext4: delayed allocation support and mmap Hi All, Current ext4_page_mkwrite() implementation always allocates a block through ext4_get_block_write() or ext4_get_block(). Commit: 9ea7df534ed2a18157434a496a12cf073ca00c52 removed the calls to write_begin() to avoid calling ext4_da_write_begin() as calling it from here is racy. So for now, in ext4: delayed allocation is not supported under an mmap call?
