Limits of BTRFS_IOC_LOGICAL_INO & BTRFS_IOC_INO_PATHS

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



I was experimenting with the BTRFS_IOC_LOGICAL_INO &
BTRFS_IOC_INO_PATHS ioctls and noticed that there are some limits in
the kernel that limit the number or results they return. For example,
for BTRFS_IOC_LOGICAL_INO, the structure that will hold the results
can be up to 65536 bytes. Are there any plans to provide an
alternative way to access that information without the aforementioned
limits? This would be useful, for example, for userspace dedup
applications.
