ext4: add missing kfree() on error return path in add_new_gdb()

2011-07-30T16:58:41+00:00

We added some more error handling in b40971426a "ext4: add error
checking to calls to ext4_handle_dirty_metadata()".  But we need to
call kfree() as well to avoid a memory leak.

ext4: simplify parameters of reserve_backup_gdb()

2011-07-28T01:23:13+00:00

The reserve_backup_gdb() function only needs the block group number;
there's no need to pass a pointer to struct ext4_new_group_data to it.

ext4: simplify parameters of add_new_gdb()

2011-07-28T01:16:33+00:00

add_new_gdb() only needs the block group number; there is no need to
pass a pointer to struct ext4_new_group_data to add_new_gdb().
Instead of filling in a pointer the struct buffer_head in
add_new_gdb(), it's simpler to have the caller fetch it from the
s_group_desc[] array.

[Fixed error path to handle the case where struct buffer_head *primary
 hasn't been set yet. -- Ted]

ext4: remove lock_buffer in bclean() and setup_new_group_blocks()

2011-07-28T00:40:18+00:00

There is no need to lock the buffers since no one else should be
touching these buffers besides the file system.

ext4: simplify journal handling in setup_new_group_blocks()

2011-07-27T02:24:41+00:00

This patch simplifies journal handling in setup_new_group_blocks().

In previous code, block bitmap is modified everywhere in
setup_new_group_blocks(), ext4_get_write_access() in
extend_or_restart_transaction() is used to guarantee that the block
bitmap stays in the new handle, this makes things complicated.

The previous commit changed things so that the modifications on the
block bitmap are batched and done by ext4_set_bits() at the end of the
for loop.  This allows us to simplify things.

ext4: let setup_new_group_blocks() set multiple bits at a time

2011-07-27T02:05:53+00:00

Rename mb_set_bits() to ext4_set_bits() and make it a global function
so that setup_new_group_blocks() can use it.

ext4: let ext4_group_add_blocks() return an error code

2011-07-27T01:46:07+00:00

This patch lets ext4_group_add_blocks() return an error code if it
fails, so that upper functions can handle error correctly.
