Convert 'alloc_obj' family to use the new default GFP_KERNEL argument

This was done entirely with mindless brute force, using git grep -l '\

treewide: Replace kmalloc with kmalloc_obj for non-scalar types

2026-02-21T09:02:28+00:00

This is the result of running the Coccinelle script from scripts/coccinelle/api/kmalloc_objs.cocci. The script is designed to avoid scalar types (which need careful case-by-case checking), and instead replace kmalloc-family calls that allocate struct or union object instances: Single allocations: kmalloc(sizeof(TYPE), ...) are replaced with: kmalloc_obj(TYPE, ...) Array allocations: kmalloc_array(COUNT, sizeof(TYPE), ...) are replaced with: kmalloc_objs(TYPE, COUNT, ...) Flex array allocations: kmalloc(struct_size(PTR, FAM, COUNT), ...) are replaced with: kmalloc_flex(*PTR, FAM, COUNT, ...) (where TYPE may also be *VAR) The resulting allocations no longer return "void *", instead returning "TYPE *". Signed-off-by: Kees Cook

move asm/unaligned.h to linux/unaligned.h

2024-10-02T21:23:23+00:00

asm/unaligned.h is always an include of asm-generic/unaligned.h; might as well move that thing to linux/unaligned.h and include that - there's nothing arch-specific in that header. auto-generated by the following: for i in `git grep -l -w asm/unaligned.h`; do sed -i -e "s/asm\/unaligned.h/linux\/unaligned.h/" $i done for i in `git grep -l -w asm-generic/unaligned.h`; do sed -i -e "s/asm-generic\/unaligned.h/linux\/unaligned.h/" $i done git mv include/asm-generic/unaligned.h include/linux/unaligned.h git mv tools/include/asm-generic/unaligned.h tools/include/linux/unaligned.h sed -i -e "/unaligned.h/d" include/asm-generic/Kbuild sed -i -e "s/__ASM_GENERIC/__LINUX/" include/linux/unaligned.h tools/include/linux/unaligned.h

fs/adfs: map: fix map scanning

2020-01-21T01:12:40+00:00

When scanning the map for a fragment id, we need to keep track of the free space links, so we don't inadvertently believe that the freespace link is a valid fragment id. Signed-off-by: Russell King Signed-off-by: Al Viro

fs/adfs: map: move map-specific sb initialisation to map.c

2020-01-21T01:12:40+00:00

Move map specific superblock initialisation to map.c, rather than having it spread into super.c. Signed-off-by: Russell King Signed-off-by: Al Viro

fs/adfs: map: use find_next_bit_le() rather than open coding it

2020-01-21T01:12:40+00:00

Use find_next_bit_le() to find the end of a fragment in the map rather than open-coding this functionality. Signed-off-by: Russell King Signed-off-by: Al Viro

fs/adfs: map: incorporate map offsets into layout

2020-01-21T01:12:40+00:00

lookup_zone() and scan_free_map() cope in different ways with the location of the map data within a zone: 1. lookup_zone() adds a four byte offset to the map data pointer to skip over the check and free link bytes. 2. scan_free_map() needs to use the free link pointer, which is an offset from itself, so we end up adding a 32-bit offset to the end pointer (aka mapsize) which is really confusing. Rename mapsize to endbit as this is really what it is, and incorporate the 32-bit offset into the map layout. This means that both dm_startbit and dm_endbit are now bit offsets from the start of the buffer, rather than four bytes in to the buffer. Signed-off-by: Russell King Signed-off-by: Al Viro

fs/adfs: map: factor out map cleanup

2020-01-21T01:12:40+00:00

We have several places which deal with releasing the map buffers and freeing the map array. Provide a helper for this. Signed-off-by: Russell King Signed-off-by: Al Viro

fs/adfs: map: break up adfs_read_map()

2020-01-21T01:12:40+00:00

Split up adfs_read_map() into separate helpers to layout the map, read the map, and release the map buffers. Signed-off-by: Russell King Signed-off-by: Al Viro

fs/adfs: map: rename adfs_map_free() to adfs_map_statfs()

2020-01-21T01:12:40+00:00

adfs_map_free() is not obvious whether it is freeing the map or returning the number of free blocks on the filesystem. Rename it to the more generic statfs() to make it clear that it's a statistic function. Signed-off-by: Russell King Signed-off-by: Al Viro
