similar to: [PATCH 1/2] loop: fix loop_info struct

The structure definition in the header, does not match the kernel's definition (on most architectures) which leads to undefined behaviour.

linux/loop.h header is exported by linux, for userspace to consume. This would prevent issues with struct sizes incompatibilities.

Hi, I wanted to create a new btrfs fs for my backups. When trying to mkfs.btrfs for that device, I''m getting "error checking /dev/loop2 mount status" With strace I see where the problem is: lstat("/dev/disk/by-id/ata-INTEL_SSDSA2M160G2GC_CVPO939201JX160AGN-par", 0x7fffa30b3cf0) = -1 ENOENT (No such file or directory) The problem is there is something missing

Hello, Happy New Year! These patches make syslinux/linux support ext2/3/4, and it doesn't require the root privilege, I'd like to add a separate e2fs/syslinux, if that is more appropriate, it should be easy to do that. I put these patches on github so that you can easily get them in case you'd like to test them. (The repo's name is sys_tmp, which avoids confusing others, I will

This set of patches add some support for sector size >512. Currently it fixes extlinux, MBR for GPT and ext partitions. Other code is unaffected. This set of patches has been tested on a read Dell machine running a beta firmware.

Hi, Gang: I remember there were different voices when you check-in the code. I agree with them although I didn't reply your mail in open64's mailing list. In the transformation you illustrate, it involves two operations: 1) promote WHILE-loop into DO-loop (i.e noncountable loop to countable loop) 2) get rid of trip-count dec/inc and compare. 1) is irrelevant to HW loop.

I am the designer for open64 hwloop structure, but I am not a student. Hope the following helps: To transform a loop into hwloop, we need the help from optimizer. For example, while(k3>=10){ sum+=k1; k3 --; } into the form: zdl_loop(k3-9) { sum+=k1; } So, we introduce a new ZDLBR whirl(open64 optimizer intermediate) operator, which represents the loop in whirl as:

Hi, I found a bug in extlinux/main.c. Writing a bootloader on a file mounted via /dev/mapper in Lunix it crashed on me with a segment fault. The bug is here: if (!ioctl(devfd, HDIO_GETGEO, &geo)) { Since we are already called with geo as a pointer the & is wrong as the pointer itself will be overwritten. This works: int get_geometry(int devfd, uint64_t totalbytes, struct

Hi shuxin, Promote while-loop to do-loop is the job of loop induction recognized, not this transformation. The scalar transform for hwloop in optimizer is for that it is a trouble to discriminate trip counting code with the real production code stuff and do the elimination in cg, we have to write customized code to handle this general stuff in ervey targets. So, we take the help from optimizer

Some programs like btrfsck should not be run on a mounted filesystem. This patch adds a check in btrfs_open_devices() for the mount status of every device belonging to the filesystem. The function check_mount() gets improved support for loopback devices. It now detects if the program is run on the file that is being used by the loopback device. Signed-off-by: Andi Drebes
