| |
Undocument the non-working resize= mount option in ext3, and add some references to the ext2resize package instead, which appears to be the only proper way of doing online resizing of ext3 filesystems.

I first thought online resizing was supposed to be done like in JFS (using mount -o remount,resize=nblocks), and fixed fs/ext3/super.c so the resize option was recognized properly. However, the feature simply didn't work (mount ended up in blocking I/O sleep with nothing happening), so I assume the option is intentionally disabled.
