Hi,
The free bitmap is called from fill_segs(). The page for free bitmap
may be used recursively. We have to care this point.
lock_page(bitmap page (e.g. index == 3))
->writepage(bitmap page)
tux3_get_block()
balloc() (allocate blocks for that bitmap page)
/* we are starting to find free block on bitmap */
while (end of page)
blockread(bitmap page)
lock_page(bitmap page (index == 3))
Current blockread() have the above deadlock. This patchset is including
the hack to avoid this. Later, we should revisit blockread() to fix
properly.
Second one is dleaf_merge() fix. Now, it don't care about
MAX_GROUP_ENTRIES at all. This fixes it.
