Subject: Fix a bug in committing of dirty inodes to stable storage.
X-Git-Url: http://git.vrable.net/?a=commitdiff_plain;h=d2e23899649c348326f306b61d12fbd4f6fb0b66;hp=d7d143ef0ccf0f49a8fd23a3c76bc68c0b04e07e;p=bluesky.git

Fix a bug in committing of dirty inodes to stable storage.

Previously, if an inode changed while it was being committed, we would
stall all future commits.  Now allow those commits to proceed once the
first commit is done.
