Subject: [PATCH 01/11] ext3: Get rid of extenddisksize parameter of ext3_get_blocks_handle()
Date: Mon, 15 Jun 2009 19:59:48 +0200	[thread overview]
Message-ID: <1245088797-29533-2-git-send-email-jack@suse.cz> (raw)
In-Reply-To: <1245088797-29533-1-git-send-email-jack@suse.cz>

Get rid of extenddisksize parameter of ext3_get_blocks_handle(). This seems to
be a relict from some old days and setting disksize in this function does not
make much sence. Currently it was set only by ext3_getblk().  Since the
parameter has some effect only if create == 1, it is easy to check that the
three callers which end up calling ext3_getblk() with create == 1 (ext3_append,
ext3_quota_write, ext3_mkdir) do the right thing and set disksize themselves.
