* [PATCH] fuse: add bmap supportMiklos Szeredi2006-12-07
| | | | | | | | | Add support for the BMAP operation for block device based filesystems. This is needed to support swap-files and lilo. Signed-off-by: Miklos Szeredi <miklos@szeredi.hu> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
* [PATCH] fuse: add blksize optionMiklos Szeredi2006-12-07
| | | | | | | | | | Add 'blksize' option for block device based filesystems. During initialization this is used to set the block size on the device and the super block. The default block size is 512bytes. Signed-off-by: Miklos Szeredi <miklos@szeredi.hu> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
* [PATCH] fuse: add support for block device based filesystemsMiklos Szeredi2006-12-07
| | | | | | | | | | | | | | | | | | 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] fuse: minor cleanup in fuse_dentry_revalidateMiklos Szeredi2006-12-07

* [PATCH] Fix check_partition routinesSuzuki K P2006-12-07
| | | | | | | | | | | | | | | | | 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 Kp2006-12-07
| | | | | | | | | | | | | | | | | | | | | | | | | 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.

* [PATCH] Allow user processes to raise their oom_adj valueGuillem Jover2006-12-07
| | | | | | | | | | | | | | | | | | Currently a user process cannot rise its own oom_adj value (i.e. unprotecting itself from the OOM killer). As this value is stored in the task structure it gets inherited and the unprivileged childs will be unable to rise it. The EPERM will be handled by the generic proc fs layer, as only processes with the proper caps or the owner of the process will be able to write to the file. So we allow only the processes with CAP_SYS_RESOURCE to lower the value, otherwise it will get an EACCES which seems more appropriate than EPERM.

* [PATCH] skip data conversion in compat_sys_mount when data_page is NULLAndrey Mirkin2006-12-07
| | | | | | | | | | | | | | | | | | | OpenVZ Linux kernel team has found a problem with mounting in compat mode. Simple command "mount -t smbfs ..." on Fedora Core 5 distro in 32-bit mode leads to oops: Unable to handle kernel NULL pointer dereference at 0000000000000000 RIP: compat_sys_mount+0xd6/0x290 Process mount (pid: 14656, veid=300, threadinfo ffff810034d30000, task ffff810034c86bc0) Call Trace: ia32_sysret+0x0/0xa The problem is that data_page pointer can be NULL, so we should skip data conversion in this case.
