2006-03-09JFS: add uid, gid, and umask mount optionsDave Kleikamp
OS/2 doesn't initialize the uid, gid, or unix-style permission bits. The uid, gid, & umask mount options perform pretty much like those for the fat file system, overriding what is stored on disk. This is useful for users sharing the file system with OS/2. I implemented a little feature so that if you mask the execute bit, it will be re-enabled on directories when the appropriate read bit is unmasked. I didn't want to implement an fmask & dmask option.

2006-01-08[PATCH] Fix and add EXPORT_SYMBOL(filemap_write_and_wait)OGAWA Hirofumi
This patch add EXPORT_SYMBOL(filemap_write_and_wait) and use it. See mm/filemap.c: And changes the filemap_write_and_wait() and filemap_write_and_wait_range(). Current filemap_write_and_wait() doesn't wait if filemap_fdatawrite() returns error. However, even if filemap_fdatawrite() returned an error, it may have submitted the partially data pages to the device. (e.g. in the case of -ENOSPC) <quotation> Andrew Morton writes, If filemap_fdatawrite() returns an error, this might be due to some I/O problem: dead disk, unplugged cable, etc. Given the generally crappy quality of the kernel's handling of such exceptions, there's a good chance that the filemap_fdatawait() will get stuck in D state forever. </quotation> So, this patch doesn't wait if filemap_fdatawrite() returns the -EIO. Trond, could you please review the nfs part? Especially I'm not sure, nfs must use the "filemap_fdatawrite(inode->i_mapping) == 0", or not.

2005-10-03JFS: make special inodes play nicely with page balancingDave Kleikamp
This patch fixes up a few problems with jfs's reserved inodes. 1. There is no need for the jfs code setting the I_DIRTY bits in i_state. I am ashamed that the code ever did this, and surprised it hasn't been noticed until now. 2. Make sure special inodes are on an inode hash list. If the inodes are unhashed, __mark_inode_dirty will fail to put the inode on the superblock's dirty list, and the data will not be flushed under memory pressure. 3. Force writing journal data to disk when metapage_writepage is unable to write a metadata page due to pending journal I/O. Signed-off-by: Dave Kleikamp <shaggy@austin.ibm.com>
2005-06-27JFS: Code cleanup - getting rid of never-used debug codeDave Kleikamp
I'm finally getting around to cleaning out debug code that I've never used. There has always been code ifdef'ed out by _JFS_DEBUG_DMAP, _JFS_DEBUG_IMAP, _JFS_DEBUG_DTREE, and _JFS_DEBUG_XTREE, which I have personally never used, and I doubt that anyone has since the design stage back in OS/2. There is also a function, xtGather, that has never been used, and I don't know why it was ever there. Signed-off-by: Dave Kleikamp <shaggy@austin.ibm.com>

2005-05-02[PATCH] JFS: Simplify creation of new iagDave Kleikamp
JFS was creating a new IAG (inode aggregate group) in one address space, and afterwards, accessing it from another. This could lead to complications when cache pages contain more than one page of jfs metadata. This patch causes the IAG to be initialized in the same address space that it is subsequently accessed with. This also elimitates an I/O, but IAG's aren't created too often.

2005-04-16Linux-2.6.12-rc2Linus Torvalds
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!
