One of the return statements in search_dir() didn't free everything it
was supposed to.

-EBUSY is platform dependent and is even less reliable when truncated to
a u8. Just return 1 on error.

btrfs_free_path() derefs the path before freeing it. It can't be passed
a null pointer when allocation fails.

'next' can never be non-null in the body of these loops. It's
initialized to NULL and the loop is terminated the moment it is set.

copy_one_inline() meant to test the return of pwrite() with ram_size.
Presumably the comparison with len was copied from the test earlier in
the function.

The mount status is checked against the arg <device> (argv[optind]),
not the <directory>. Correct the info printed on <device> mounted.

The kernel uses unsigned long long for u64, but PPC64 uses unsigned
long by default. This results in compilation warnings such as:
print-tree.c:333: warning: format '%llu' expects type 'long long
unsigned int', but argument 4 has type 'u64'
To fix this, the macro __KERNEL__ needs to be defined before including
the file <asm/types.h>. This can be done by defining the macro in
"kerncompat.h" and making it the first included file in the relevant
header files; this fixes the compiler warnings on PPC64.

Given a zero-length directory name, the trailing-slash removal
code would test dir_name[-1], and if it were found to be a slash,
would set it to '\0'.

This changes restore to set the i_size of the files it
copies out based on the size in the inode. It also changes
it to skip over holes.
