fs: change d_hash for rcu-walk

2011-01-07T06:50:20+00:00

Change d_hash so it may be called from lock-free RCU lookups. See similar
patch for d_compare for details.

For in-tree filesystems, this is just a mechanical change.

fs: change d_compare for rcu-walk

2011-01-07T06:50:19+00:00

Change d_compare so it may be called from lock-free RCU lookups. This
does put significant restrictions on what may be done from the callback,
however there don't seem to have been any problems with in-tree fses.
If some strange use case pops up that _really_ cannot cope with the
rcu-walk rules, we can just add new rcu-unaware callbacks, which would
cause name lookup to drop out of rcu-walk mode.

For in-tree filesystems, this is just a mechanical change.

hfsplus: use atomic bitops for the superblock flags

2010-10-01T03:45:20+00:00

The flags in the HFS+-specific superlock do get modified during runtime,
use atomic bitops to make the modifications SMP safe.

hfsplus: fix HFSPLUS_SB calling convention

2010-10-01T03:42:59+00:00

HFSPLUS_SB doesn't return a pointer to the hfsplus-specific superblock
information like all other FOO_SB macros, but dereference the pointer in a way
that made it look like a direct struct derefence.  This only works as long
as the HFSPLUS_SB macro is used directly and prevents us from keepig a local
hfsplus_sb_info pointer.  Fix the calling convention and introduce a local
sbi variable in all functions that use it constantly.

HFS+: add custom dentry hash and comparison operations

2007-07-16T16:05:49+00:00

Add custom dentry hash and comparison operations for HFS+ filesystems that are
case-insensitive and/or do automatic unicode decomposition.  The new
operations reuse the existing HFS+ ASCII to unicode conversion, unicode
decomposition and case folding functionality.

HFS+: refactor ASCII to unicode conversion routine for later reuse

2007-07-16T16:05:49+00:00

The HFS+ filesystem is case-insensitive and does automatic unicode
decomposition by default, but does not provide custom dentry operations.  This
can lead to multiple dentries being cached for lookups on a filename with
varying case and/or character (de)composition.

These patches add custom dentry hash and comparison operations for
case-sensitive and/or automatically decomposing HFS+ filesystems.  Unicode
decomposition and case-folding are performed as required to ensure equivalent
filenames are hashed to the same values and compare as equal.

This patch:

Refactor existing HFS+ ASCII to unicode string conversion routine to split out
character conversion functionality.  This will be reused by the custom dentry
hash and comparison routines.  This approach avoids unnecessary memory
allocation compared to using the string conversion routine directly in the new
functions.
