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!

udf: Don't write integrity descriptor too often We update information in logical volume integrity descriptor after each allocation (as LVID contains free space, number of directories and files on disk etc.). If the filesystem is on some phase change media, this leads to its quick degradation as such media is able to handle only 10000 overwrites or so. We solve the problem by writing new information into LVID only on umount, remount-ro and sync. This solves the problem at the price of longer media inconsistency (previously media became consistent after pdflush flushed dirty LVID buffer) but that should be acceptable.

udf: Fix 64-bit sign extension issues affecting blocks > 0x7FFFFFFF Large (> 1 TiB) UDF filesystems appear subject to several problems when mounted on 64-bit systems: * readdir() can fail on a directory containing File Identifiers residing above 0x7FFFFFFF. This manifests as a 'ls' command failing with EIO. * FIBMAP on a file block located above 0x7FFFFFFF can return a negative value. The low 32 bits are correct, but applications that don't mask the high 32 bits of the result can perform incorrectly. Per suggestion by Jan Kara, introduce a udf_pblk_t type for representation of UDF block addresses. Ultimately, all driver functions that manipulate UDF block addresses should use this type; for now, deployment is limited to functions with actual or potential sign extension issues. Changes to udf_readdir() and udf_block_map() address the issues noted above; other changes address potential similar issues uncovered during audit of the driver code. Signed-off-by: Steven J.

[PATCH] udf: initialize parts of inode earlier in create I saw an oops down this path when trying to create a new file on a UDF filesystem which was internally marked as readonly, but mounted rw: udf_create udf_new_inode new_inode alloc_inode udf_alloc_inode udf_new_block returns EIO due to readonlyness iput (on error) udf_put_inode udf_discard_prealloc udf_next_aext udf_current_aext udf_get_fileshortad OOPS the udf_discard_prealloc() path was examining uninitialized fields of the udf inode. udf_discard_prealloc() already has this code to short-circuit the discard path if no extents are preallocated: if (UDF_I_ALLOCTYPE(inode) == ICBTAG_FLAG_AD_IN_ICB || inode->i_size == UDF_I_LENEXTENTS(inode)) { return; } so if we initialize UDF_I_LENEXTENTS(inode) = 0 earlier in udf_new_inode, we won't try to free the (not) preallocated blocks, since this will match the i_size = 0 set when the inode was initialized.

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!

fs: Replace current_fs_time() with current_time() current_fs_time() uses struct super_block* as an argument. As per Linus's suggestion, this is changed to take struct inode* as a parameter instead. This is because the function is primarily meant for vfs inode timestamps. Also the function was renamed as per Arnd's suggestion. Change all calls to current_fs_time() to use the new current_time() function instead. current_fs_time() will be deleted.

udf: fix the udf_iget() vs. udf_new_inode() races Currently udf_iget() (triggered by NFS) can race with udf_new_inode() leading to two inode structures with the same inode number: nfsd: iget_locked() creates inode nfsd: try to read from disk, block on that. udf_new_inode(): allocate inode with that inumber udf_new_inode(): insert it into icache, set it up and dirty udf_write_inode(): write inode into buffer cache nfsd: get CPU again, look into buffer cache, see nice and sane on-disk inode, set the in-core inode from it Fix the problem by putting inode into icache in locked state (I_NEW set) and unlocking it only after it's fully set up.
