[PATCH 0/9] nilfs2: introduce functionality of creation of sysfs groups and attributes

[Vyacheslav Dubeyko]

Hi,

This patchset implements creation of sysfs groups and attributes with
the purpose to show NILFS2 volume details and internal state of
the driver.

Implemented functionality creates such groups:
(1) /sys/fs/nilfs - root group
(2) /sys/fs/nilfs/features - group contains attributes that describe NILFS
file system driver features
(3) /sys/fs/nilfs/<device> - group contains attributes that describe file
system partition's details
(4) /sys/fs/nilfs/<device>/superblock - group contains attributes that describe
superblock's details
(5) /sys/fs/nilfs/<device>/segctor - group contains attributes that describe
segctor thread activity details
(6) /sys/fs/nilfs/<device>/segments - group contains attributes that describe
details about volume's segments
(7) /sys/fs/nilfs/<device>/checkpoints - group contains attributes that describe
details about volume's checkpoints
(8) /sys/fs/nilfs/<device>/mounted_snapshots - group contains group for every
mounted snapshot
(9) /sys/fs/nilfs/<device>/mounted_snapshots/<snapshot> - group contains
details about mounted snapshot

With the best regards,
Vyacheslav Dubeyko.
