Subject: [PATCH 0/2] jffs2: fixes for file creation failed halfway

Hi,

There are the fixes for file creation which failed halfway, the first
one is used to reclaim flash spaces had been used by the inode, and
the second one fixes a BUG assertion in jffs2_do_read_inode().

These two problems can be reproduced by concurrently creating files
until no space is left, and then removing these files, and repeating.

Comments are welcome.
