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

kernel.h: drop hex.h and update all hex.h users

2026-01-21T03:44:19+00:00

Remove from and update all users/callers of hex.h interfaces to directly #include as part of the process of putting kernel.h on a diet. Removing hex.h from kernel.h means that 36K C source files don't have to pay the price of parsing hex.h for the roughly 120 C source files that need it. This change has been build-tested with allmodconfig on most ARCHes. Also, all users/callers of in the entire source tree have been updated if needed (if not already #included).

fs/adfs: mostly divorse inode number from indirect disc address

2020-01-21T01:12:42+00:00

Avoid using the inode number as the indirect disc address, even though these currently have the same value. Signed-off-by: Russell King Signed-off-by: Al Viro

fs/adfs: dir: remove debug in adfs_dir_update()

fs/adfs: newdir: split out directory commit from update

2020-01-21T01:12:42+00:00

After changing a directory, we need to update the sequence numbers and calculate the new check byte before the directory is scheduled to be written back to the media. Since this needs to happen for any change to the directory, move this into a separate method. Signed-off-by: Russell King Signed-off-by: Al Viro

fs/adfs: dir: add more efficient iterate() per-format method

2020-01-21T01:12:41+00:00

Rather than using setpos + getnext to iterate through the directory entries, pass iterate() down to the dir format code to populate the dirents. Signed-off-by: Russell King Signed-off-by: Al Viro

fs/adfs: dir: switch to iterate_shared method

2020-01-21T01:12:41+00:00

There is nothing in our readdir (aka iterate) method that relies on the directory inode being exclusively locked, so switch to using the iterate_shared() hook rather than iterate(). Signed-off-by: Russell King Signed-off-by: Al Viro

fs/adfs: dir: improve compiler coverage in adfs_dir_update

2020-01-21T01:12:41+00:00

Get rid of the ifdef, using IS_ENABLED() instead to detect whether the code should be callable. This allows the compiler to always parse the following code, reducing the chances of errors being missed. Signed-off-by: Russell King Signed-off-by: Al Viro

fs/adfs: dir: improve update failure handling

2020-01-21T01:12:41+00:00

When we update a directory, a number of errors may happen. If we failed to find the entry to update, we can just release the directory buffers as normal. However, if we have some other error, we may have partially updated the buffers, resulting in an invalid directory. In this case, we need to discard the buffers to avoid writing the contents back to the media, and later re-read the directory from the media. Signed-off-by: Russell King Signed-off-by: Al Viro
