A couple of questions

false-negative results due to the filesystem cache (although btrfs may remove
this risk).
Another approach would be to ask btrfs for the checksum. It seems that it''s
possible to combine multiple CRC-32C values to figure out the checksum of the
combined data [e.g., zlib''s crc32_combine() function]. So, obtaining a file''s
checksum might be a light-weight operation.
Yet another possibility would be to push the desired checksum value (via
fcntl?) and have btrfs compare the desired checksum with the file''s actual
checksum on close(2), failing that call if the c...

[PATCH 00/12] Multidisk support
Hello,
the following patches should get multidisk access working.
The syntax accepted is the following:
(hdx,y)/path/to/file
where x is the disk number and start at 0 and the y is the partition number starting at 1. So (hd0,1) is the first partition of the first disk.
the other accepted syntax is using MBR's 32 bits disk signature so for example:
(mbr:0x12345678,2)/foo/bar
would address
