Hi all -
The following are a series of patches that have been kicking around for a
while. I thought I'd just put them out there to gauge interest and to get
some testing before submitting to -mm.
There are a few groups:
* Little changes (01,02,09)
- Fixes lockdep warnings in xattr code
- Changes reiserfs_panic() to panic() instead of BUG.
- Includes bitmap is_reusable unconditionally and uses to to catch
corruption. This is light-weight now that the stupid loop is gone.
- Make bitmap used cached first zero bit.
* Error handling (03-08)
- Reformat error/warning/panic/info/etc messages to be consistent with one
another.
- Makes some warnings informational. Rather than printing the
reiserfs_warning() full preamble to declare that a mount option was
invalid, we use reiserfs_info instead.
- Rework reiserfs_warning to take a unique ID, print the function name,
print the device name.
- Rework reiserfs_panic similarly.
- Add reiserfs_error() to handle metadata errors.
- Use reiserfs_error().
* Extended attributes (11-21)
- Simplify internal file lookups/opens
- Eliminate per-super xattr lock
- Make per-inode xattr lock more fine-grained
- Remove i_has_xattr_dir flag
- Remove shared xattr detection (unused)
- Use generic xattr handler infrastructure
- Use O_NOATIME for internal file opens
- Add per-file data=ordered mode and use it for xattrs
- Journal xattrs
- Kill xattr_readdir in favor of a for_each_xattr
- Add atomic addition of selinux attributes during inode creation
* Cleanups, code readability (22-29)
- Cleanup path functions to reduce redundancy
- Strip trailing whitespace from all reiserfs code
- Rename p_s_sb to sb
- Rename p_s_bh to bh
- Rename p_s_inode to inode
- Rename p_s_tb to tb
- Rename misc p_._ variables
- Rename [cn]_* variables
* Clean up do_balan.c (30-39)
- Factor out buffer_info initializations
- Turn tb->s[12]num and tb[12]bytes into an array
- Split balance_leaf from the 2500 line beast to more manageable chunks
- Clean up balance_leaf_when_delete
- Clean up comments
I look forward to comments. The journaled xattr changes in particular need
testing as deadlocks may still lurk in there.
I've also posted the patch set here:
