2008-08-16ext4: Use ext4_discard_reservations instead of mballoc-specific callTheodore Ts'o
In ext4_ext_truncate(), we should use the more generic ext4_discard_reservations() call so we do the right thing when the filesystem is mounted with the nomballoc option. Signed-off-by: "Theodore Ts'o" <tytso@mit.edu> Reviewed-by: Mingming Cao <cmm@us.ibm.com>

2008-08-19ext4: Fix delalloc release block reservation for truncateMingming Cao
Ext4 will release the reserved blocks for delayed allocations when inode is truncated/unlinked. If there is no reserved block at all, we shouldn't need to do so. But current code still tries to release the reserved blocks regardless whether the counters's value is 0. Continue to do that causes the later calculation to go wrong and a kernel BUG_ON() caught that. This doesn't happen for extent-based files, as the calculation for 0 reserved blocks was right for extent based file. This patch fixed the kernel BUG() due to above reason. It adds checks for 0 to avoid unnecessary release and fix calculation for non-extent files. Signed-off-by: Mingming Cao <cmm@us.ibm.com> Signed-off-by: "Theodore Ts'o" <tytso@mit.edu>
2008-08-13ext4: Fix potential truncate BUG due to i_prealloc_list being non-emptyTheodore Ts'o
We need to call ext4_discard_reservation() earlier in ext4_truncate(), to avoid a BUG() in ext4_mb_return_to_preallocation(), which is called (ultimately) by ext4_free_blocks(). So we must ditch the blocks on i_prealloc_list before we start freeing the data blocks. Signed-off-by: "Theodore Ts'o" <tytso@mit.edu>
2008-08-19ext4: Handle unwritten extent properly with delayed allocationAneesh Kumar K.V
When using fallocate the buffer_heads are marked unwritten and unmapped. We need to map them in the writepages after a get_block. Otherwise we split the uninit extents, but never write the content to disk.

2008-08-12seq_file: add seq_cpumask(), seq_nodemask()Alexey Dobriyan
Short enough reads from /proc/irq/*/smp_affinity return -EINVAL for no good reason. This became noticed with NR_CPUS=4096 patches, when length of printed representation of cpumask becase 1152, but cat(1) continued to read with 1024-byte chunks. bitmap_scnprintf() in good faith fills buffer, returns 1023, check returns -EINVAL. Fix it by switching to seq_file, so handler will just fill buffer and doesn't care about offsets, length, filling EOF and all this crap. For that add seq_bitmap(), and wrappers around it -- seq_cpumask() and seq_nodemask().

2008-08-06[CIFS] cifs_mkdir and cifs_create should respect the setgid bit on parent dirJeff Layton
If a server supports unix extensions but does not support POSIX create routines, then the client will create a new inode with a standard SMB mkdir or create/open call and then will set the mode. When it does this, it does not take the setgid bit on the parent directory into account. This patch has CIFS flip on the setgid bit when the parent directory has it. If the share is mounted with "setuids" then also change the group owner to the gid of the parent. This patch should apply cleanly on top of the setattr cleanup patches that I sent a few weeks ago.

Which stayed unnoticed for a long time because, surprise, idr_remove() masks out that high bit before doing anything. All of this due to "| ~MAX_ID_MASK" in release_inode_number(). I still don't understand how it's supposed to work, because "| ~MASK" is not an inversion for "& MAX" operation. So, use just one nice, working addition.
