When a node contains only HighMem memory, slab_node(MPOL_BIND) dereferences a NULL pointer. [ This code seems to go back all the way to commit 19770b32: "mm: filter based on a nodemask as well as a gfp_mask". Which was back in April 2008, and it got merged into 2.6.26. - Linus ] Signed-off-by:

Commit 5dabfc78 ("ext4: rename {exit,init}_ext4_*() to ext4_{exit,init}_*()") causes fs/ext4/super.c:4776: error: implicit declaration of function ‘ext4_init_xattr’ when CONFIG_EXT4_FS_XATTR is disabled. It renamed init_ext4_xattr to ext4_init_xattr but forgot to update the dummy definition in fs/ext4/xattr.h. Signed-off-by:

Commit 3e4d3af5 ("mm: stack based kmap_atomic()") overlooked the fact that parisc uses kmap as a coherence mechanism, so even though we have no highmem, we do need to supply our own versions of kmap (and atomic). This patch converts the parisc kmap to the form which is needed to keep it compiling (it's a simple prototype and name change). Signed-off-by:

Today's git tree fails to build on !CONFIG_BLOCK, due to upstream commit 367a51a3 ("fs: Add FITRIM ioctl"): include/linux/fs.h:36: error: expected specifier-qualifier-list before ‘uint64_t’ include/linux/fs.h:36: error: expected specifier-qualifier-list before ‘uint64_t’ include/linux/fs.h:36: error: expected specifier-qualifier-list before ‘uint64_t’ The commit adds uint64_t type usage to fs.h, but linux/types.h is not included explicitly - it's only included implicitly via linux/blk_types.h, and there only if CONFIG_BLOCK is enabled. Add the explicit #include to fix this. Signed-off-by:

SYNOPSIS size[4] Tfsync tag[2] fid[4] datasync[4] size[4] Rfsync tag[2] DESCRIPTION The Tfsync transaction transfers ("flushes") all modified in-core data of file identified by fid to the disk device (or other permanent storage device) where that file resides. If datasync flag is specified data will be fleshed but does not flush modified metadata unless that metadata is needed in order to allow a subsequent data retrieval to be correctly handled.

The presence of v9fs_direct_IO() in the address space ops vector allowes open() O_DIRECT flags which would have failed otherwise. In the non-cached mode, we shunt off direct read and write requests before the VFS gets them, so this method should never be called. Direct IO is not 'yet' supported in the cached mode. Hence when this routine is called through generic_file_aio_read(), the read/write fails with an error. Signed-off-by:

The current implementation of 9p client mkdir function does not set the S_ISGID mode bit for the directory being created if the parent directory has this bit set. This patch fixes this problem so that the newly created directory inherits the gid from parent directory and not from the process creating this directory, when the S_ISGID bit is set in parent directory.
