From 3bdbfb104e53b367892cc9510e6722346dfb656b Mon Sep 17 00:00:00 2001 From: David Chinner Date: Fri, 2 Sep 2005 16:40:47 +1000 Subject: [XFS] Prevent the incore superblock sb_fdblocks count from leaking when we are getting ENOSPC errors on writes. When we fail to allocate space for indirect blocks in xfs_bmapi() make sure we release the direct block allocation before returning.
