We can preallocate the node so insertion does not have to do that under the lock. The GFP flags for the global radix tree are initialized to GFP_NOFS & ~__GFP_DIRECT_RECLAIM but we can use GFP_KERNEL, because readahead is optional and not on any critical writeout path. Reviewed-by:

We can preallocate the node so insertion does not have to do that under the lock. The GFP flags for the per-device radix tree are initialized to GFP_NOFS & ~__GFP_DIRECT_RECLAIM but we can use GFP_KERNEL, same as an allocation above anyway, but also because readahead is optional and not on any critical writeout path.

The btrfs_balance_args are only used for the balance ioctl, so use __u instead of __le here for consistency. The __le usage was introduced in bc309467 and dee32d0a and was probably a result of copy/pasting when the code was written. The usage of __le did not break anything, but it's unnecessary. Also, this change makes the code less confusing for the careful reader. Signed-off-by:

Since this part is mostly independent, this moves it to a separate function. Reviewed-by:

As the part of getting extra mirror in __btrfs_map_block is independent, this puts it into a separate function. Reviewed-by:

Since DISCARD is not as important as an operation like write, we don't copy it to target device during replace, and it makes __btrfs_map_block less complex. Signed-off-by:

While debugging truncate problems, I found that these tracepoints could help us quickly know what went wrong. Two sets of tracepoints are created to track regular/prealloc file item and inline file item respectively, I put inline as a separate one since what inline file items cares about are way less than the regular one. This adds four tracepoints: - btrfs_get_extent_show_fi_regular - btrfs_get_extent_show_fi_inline - btrfs_truncate_show_fi_regular - btrfs_truncate_show_fi_inline Cc: David Sterba <dsterba@suse.cz> Signed-off-by:

refcount_t type and corresponding API should be used instead of atomic_t when the variable is used as a reference counter. This allows to avoid accidental refcounter overflows that might lead to use-after-free situations. Signed-off-by:

After 76b42abb ("Btrfs: fix data loss after truncate when using the no-holes feature"), For either NO_HOLES or inline extents, we've set last_size to newsize to avoid data loss after remount or inode got evicted and read again, thus, we don't need this check anymore. Signed-off-by:

If your filesystem has, eg, data:raid0 metadata:raid1, and you run "btrfs balance -dconvert=raid1", the meta.target field will be uninitialized. That's otherwise ok, as it's unused except for this warning. Thus, let's use the existing set of raid levels for the comparison. As a side effect, non-convert balances will now nag about data>metadata. Signed-off-by:
