    nilfs2: fix regression of garbage collection ioctl · 947b10ae
    Ryusuke Konishi authored
    On 2.6.37-rc1, garbage collection ioctl of nilfs was broken due to the
    commit 263d90ce ("nilfs2: remove own inode hash used for GC"),
    and leading to filesystem corruption.
    
    The patch doesn't queue gc-inodes for log writer if they are reused
    through the vfs inode cache.  Here, gc-inode is the inode which
    buffers blocks to be relocated on GC.  That patch queues gc-inodes in
    nilfs_init_gcinode() function, but this function is not called when
    they don't have I_NEW flag.  Thus, some of live blocks are wrongly
    overrode without being moved to new logs.
    
    This resolves the problem by moving the gc-inode queueing to an outer
    function to ensure it's done right.
