When I connect an Intel SSD to SATA SIL controller (PCI ID 1095:3114), any TRIM command results in I/O errors being reported in the log. There is other similar error reported with TRIM and the SIL controller: https://bugs.centos.org/view.php?id=5880 Apparently the controller doesn't support TRIM commands.

Current code doesn't update port value of Port Multiplier(PM) when sending FIS of softreset to device, command will fail if FBS is enabled. There are two ways to fix the issue: the first is to disable FBS before sending softreset command to PM device and the second is to update port value of PM when sending command. For the first way, i can't find any related rule in AHCI Spec. The second way can avoid disabling FBS and has better performance. Signed-off-by:

Bus errors from userspace on ARCompact based cores are handled by core as a high priority L2 interrupt but current code treated it as interrupt Handling an interrupt like exception is certainly not going to go unnoticed. (and it worked so far as we never saw a Bus error from userspace until IPPK guys tested a DDR controller with ECC error detection etc hence needed to explicitly trigger/handle such errors) - So move mem_service exception handler from common code into ARCv2 code. - In ARCompact code, define mem_service as L2 interrupt handler which just drops down to pure kernel mode and goes of to enqueue SIGBUS Reported-by:

Now that the xattr handler is passed to the xattr handler operations, we can use the same get and set operations for the user, trusted, and security xattr namespaces. In those namespaces, we can access the full attribute name by "reattaching" the name prefix the vfs has skipped for us. Add a xattr_full_name helper to make this obvious in the code. For the "system.posix_acl_access" and "system.posix_acl_default" attributes, handler->prefix is the full attribute name; the suffix is the empty string. Signed-off-by:

The xattr_handler operations are currently all passed a file system specific flags value which the operations can use to disambiguate between different handlers; some file systems use that to distinguish the xattr namespace, for example.

When a filesystem that contains POSIX ACLs is mounted without ACL support (-o noacl), the appropriate behavior is not to list any existing POSIX ACL xattrs. The return value for list xattr handlers in this case is 0, not an error code: several filesystems that use the POSIX ACL xattr handlers do not expect the list operation to fail. Symlinks cannot have ACLs, so posix_acl_xattr_list will never be called for symlinks in the first place. Signed-off-by:
