* [PATCH] Remove superfluous lock_super() in extN xattr codeAndreas Gruenbacher2006-12-073-12/+3
| | | | | | | | | | lock_super() is unnecessary for setting super-block feature flags. Use the provided *_SET_COMPAT_FEATURE() macros as well.

* [PATCH] pull in necessary header files for cdev.hJan Engelhardt2006-12-071-0/+4
| | | | | | | | | | | | linux/cdev.h uses struct kobject and other structs and should therefore include them. Currently, a module either needs to add the missing includes itself, or, in case a module includes other headers already, needs to put <linux/cdev.h> last, which goes against a alphabetically-sorted include list.

In specific, the call to ide_add_proc_entries() is unprotected, and there is nothing else in the file using the respective ->proc fields. Also the lock order around destroy_proc_ide_interface() suggests this. Alan sayeth: proc_ide_write_settings walks the setting list under ide_setting_sem, read ditto. remove_proc_entry is doing proc side housekeeping. Looks fine to me, although that old code is such a mess anything could be going on.

* [PATCH] file: kill unnecessary timer in fdtable_deferTejun Heo2006-12-071-27/+2
| | | | | | | | | | | | | | | | | | free_fdtable_rc() schedules timer to reschedule fddef->wq if schedule_work() on it returns 0. However, schedule_work() guarantees that the target work is executed at least once after the scheduling regardless of its return value. 0 return simply means that the work was already pending and thus no further action was required. Another problem is that it used contant '5' as @expires argument to mod_timer(). Kill unnecessary fddef->timer.

* [PATCH] fuse: add support for block device based filesystemsMiklos Szeredi2006-12-072-11/+53
| | | | | | | | | | | | | | | | | | I never intended this, but people started using fuse to implement block device based "real" filesystems (ntfs-3g, zfs). The following four patches add better support for these kinds of filesystems. Unlike "normal" fuse filesystems, using this feature should require superuser privileges (enforced by the fusermount utility). Thanks to Szabolcs Szakacsits for the input and testing. This patch adds a 'fuseblk' filesystem type, which is only different from the 'fuse' filesystem type in how the 'dev_name' mount argument is interpreted.

* [PATCH] Fix check_partition routinesSuzuki K P2006-12-074-15/+33
| | | | | | | | | | | | | | | | | check_partition() stops its probe once it hits an I/O error from the partition checkers. This would prevent the actual partition checker getting a chance to verify the partition. So this patch lets check_partition() continue probing untill it hits a success while recording the I/O error which might have been reported by the checking routines. Also, it does some cleanup of the partition methods for ibm, atari and amiga to return -1 upon hitting an I/O error.

* [PATCH] fix rescan_partitions to return errors properlySuzuki Kp2006-12-071-1/+3
| | | | | | | | | | | | | | | | | | | | | | | | | The current rescan_partition implementation ignores the errors that comes from the lower layer. It reports success for unknown partitions as well as I/O error cases while reading the partition information. The unknown partition is not (and will not be) considered as an error in the kernel, since there are legal users of it (e.g, members of a RAID5 MD Device or a new disk which is not partitioned at all ). Changing this behaviour would scare the user about a serious problem with their disk and is not recommended. Thus for both "unknown partitions" to the Linux (eg., DEC VMS,Novell Netware) and the legal users of NULL partition, would still be reported as "SUCCESS". The patch attached here, scares the user about something which he does need to worry about. i.e, returning -EIO on disk I/O errors while reading the partition information.

| | | | | | | | | | | | Remove #define NR_CMDS and replace it w/hba[i]->nr_cmds. Most Smart Array controllers can support up to 1024 commands but the E200 family can only support 128. To prevent annoying "fifo full" messages we define nr_cmds on a per controller basis by adding it the product table.

* [PATCH] uml: use get_random_bytes() after random pool is seededJeff Dike2006-12-077-7/+7
| | | | | | | | | | | | | When the UML network driver generates random MACs for its devices, it was possible for a number of UMLs to get the same MACs because the ethernet initialization was done before the random pool was properly seeded. This patch moves the initialization later so that it gets better randomness.
