Description Stephen Tweedie 2005-02-18 09:09:45 EST

Description of problem:
On a short O_DIRECT write --- for example, when a large write is submitted but
the fs fills up halfway through --- disk blocks get allocated but the file's
i_size is not updated.  This leads e2fsck to conclude that i_size is wrong on a
subsequent fsck.

Version-Release number of selected component (if applicable):
kernel-2.6.9-5.EL

Steps to Reproduce:
1. write 1MB blocks with O_DIRECT until the fs fills up
2. fsck
  
Actual results:
Pass 1: Checking inodes, blocks, and sizes
Inode 12, i_size is 1889019101184, should be 1889019604992.  Fix? yes

Expected results:
clean fsck.

Not massively urgent --- it's really just a cosmetic issue --- but I'm opening
the bugzilla so it doesn't get forgotten about completely.
