ext2: Fix fall-through warnings for Clang

2020-11-23T09:36:53Z

In preparation to enable -Wimplicit-fallthrough for Clang, fix a warning by explicitly adding a break statement instead of just letting the code fall through to the next case.

fs/ext2: Use ext2_put_page

2020-11-13T10:19:30Z

There are 3 places in namei.c where the equivalent of ext2_put_page() is open coded on a page which was returned from the ext2_get_page() call [through the use of ext2_find_entry() and ext2_dotdot()]. Move ext2_put_page() to ext2.h and use it in namei.c Also add a comment regarding the proper way to release the page returned from ext2_find_entry() and ext2_dotdot().

ext2: don't update mtime on COW faults

2020-09-05T17:00:05Z

When running in a dax mode, if the user maps a page with MAP_PRIVATE and PROT_WRITE, the ext2 filesystem would incorrectly update ctime and mtime when the user hits a COW fault. This breaks building of the Linux kernel. How to reproduce: 1. extract the Linux kernel tree on dax-mounted ext2 filesystem 2. run make clean 3. run make -j12 4. run make -j12 at step 4, make would incorrectly rebuild the whole kernel (although it was already built in step 3). The reason for the breakage is that almost all object files depend on objtool. When we run objtool, it takes COW page fault on its .data section, and these faults will incorrectly update the timestamp of the objtool binary. The updated timestamp causes make to rebuild the whole tree. Signed-off-by: Mikulas Patocka Cc: stable@vger.kernel.org Signed-off-by: Linus Torvalds

treewide: Use fallthrough pseudo-keyword

2020-08-23T22:36:59Z

Replace the existing /* fall through */ comments and its variants with the new pseudo-keyword macro fallthrough[1]. Also, remove unnecessary fall-through markings when it is the case.
