CONFIG_JFFS2_FS_DEBUG: JFFS2 debugging verbosity (0 = quiet, 2 = noisy)

General informations

The Linux kernel configuration item CONFIG_JFFS2_FS_DEBUG has multiple definitions:

JFFS2 debugging verbosity (0 = quiet, 2 = noisy) found in fs/jffs2/Kconfig

The configuration item CONFIG_JFFS2_FS_DEBUG:

• prompt: JFFS2 debugging verbosity (0 = quiet, 2 = noisy)
• type: int
• depends on: CONFIG_JFFS2_FS
• defined in fs/jffs2/Kconfig
• found in Linux kernels: 2.6.28–2.6.39, 3.0–3.19, 4.0–4.20, 5.0–5.19, 6.0–6.12, 6.13-rc+HEAD

Help text

This controls the amount of debugging messages produced by the JFFS2 code. Set it to zero for use in production systems. For evaluation, testing and debugging, it's advisable to set it to one. This will enable a few assertions and will print debugging messages at the KERN_DEBUG loglevel, where they won't normally be visible. Level 2 is unlikely to be useful - it enables extra debugging in certain areas which at one point needed debugging, but when the bugs were located and fixed, the detailed messages were relegated to level 2.

If reporting bugs, please try to have available a full dump of the messages at debug level 1 while the misbehaviour was occurring.
