nilfs2: use root object to get ifile

2010-10-23T00:24:35Z

This rewrites functions using ifile so that they get ifile from nilfs_root object, and will remove sbi->s_ifile. Some functions that don't know the root object are extended to receive it from caller. Signed-off-by: Ryusuke Konishi

nilfs2: keep zero value in i_cno except for gc-inodes

2010-10-23T00:24:33Z

On-memory inode structures of nilfs have a member "i_cno" which stores a checkpoint number related to the inode. For gc-inodes, this field indicates version of data each gc-inode caches for GC. Log writer temporarily uses "i_cno" to transfer the latest checkpoint number. This stops the latter use and lets only gc-inodes use it. The purpose of this patch is to allow the successive change use "i_cno" for inode lookup. Signed-off-by: Ryusuke Konishi

nilfs2: rename nilfs_recover_logical_segments function

2010-07-23T01:02:09Z

The function name of nilfs_recover_logical_segments makes no sense. This changes the name into nilfs_salvage_orphan_logs to clarify the role of the function. Signed-off-by: Ryusuke Konishi

nilfs2: refactor recovery logic routines

2010-07-23T01:02:08Z

Most functions in recovery code take an argument of a super block instance or a nilfs_sb_info struct for convenience sake. This replaces them aggressively with a nilfs object by applying __bread and __breadahead against routines using sb_bread and sb_breadahead. Signed-off-by: Ryusuke Konishi

nilfs2: remove obsolete declarations of cache constructor and destructor

2010-05-31T11:50:29Z

The commit 41c88bd7 ("nilfs2: cleanup multi kmem_cache_{create,destroy} code") consolidated slab constructors and destructors used in nilfs, but it left some declarations in header files. This gets rid of the obsolete declarations. Signed-off-by: Ryusuke Konishi

nilfs2: change sc_timer from a pointer to an embedded one in struct nilfs_sc_info

2010-05-10T02:32:31Z

In nilfs_segctor_thread(), timer is a local variable allocated on stack. Its address can't be set to sci->sc_timer and passed in several procedures. It works now by chance, just because other procedures are called by nilfs_segctor_thread() directly or indirectly and the stack hasn't been deallocated yet.

nilfs2: cleanup multi kmem_cache_{create,destroy} code

2010-05-10T02:32:30Z

This cleanup patch gives several improvements: - Moving all kmem_cache_{create_destroy} calls into one place, which removes some small function calls, cleans up error check code and clarify the logic. - Mark all initial code in __init section. - Remove some very obvious comments. - Adjust some declarations. - Fix some space-tab issues.

nilfs2: move pointer to super root block into logs

2010-05-10T02:32:30Z

This moves a pointer to buffer storing super root block to each log buffer from nilfs_sc_info struct for simplicity. Signed-off-by: Ryusuke Konishi

nilfs2: remove spaces before tabs

2010-03-14T01:29:51Z

This kills the following checkpatch warnings: WARNING: please, no space before tabs #74: FILE: segment.h:74: +^Iunsigned ^I^Iflags;$ WARNING: please, no space before tabs #35: FILE: segbuf.c:35: +^Iint ^I^I^Istart, end; /* The region to be submitted */$ Signed-off-by: Ryusuke Konishi
