hfs/hfsplus: rework debug output subsystem

2025-09-24T23:30:34+00:00

Currently, HFS/HFS+ has very obsolete and inconvenient debug output subsystem. Also, the code is duplicated in HFS and HFS+ driver. This patch introduces linux/hfs_common.h for gathering common declarations, inline functions, and common short methods. Currently, this file contains only hfs_dbg() function that employs pr_debug() with the goal to print a debug-level messages conditionally. So, now, it is possible to enable the debug output by means of: echo 'file extent.c +p' > /proc/dynamic_debug/control echo 'func hfsplus_evict_inode +p' > /proc/dynamic_debug/control And debug output looks like this: hfs: pid 5831:fs/hfs/catalog.c:228 hfs_cat_delete(): delete_cat: 00,48 hfs: pid 5831:fs/hfs/extent.c:484 hfs_file_truncate(): truncate: 48, 409600 -> 0 hfs: pid 5831:fs/hfs/extent.c:212 hfs_dump_extent(): hfs: pid 5831:fs/hfs/extent.c:214 hfs_dump_extent(): 78:4 hfs: pid 5831:fs/hfs/extent.c:214 hfs_dump_extent(): 0:0 hfs: pid 5831:fs/hfs/extent.c:214 hfs_dump_extent(): 0:0 v4 Debug messages have been reworked and information about new HFS/HFS+ shared declarations file has been added to MAINTAINERS file. v5 Yangtao Li suggested to clean up debug output and fix several typos.

Linux-2.6.12-rc2

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
