Merge tag 'vfs-6.13.exec.deny_write_access.revert' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs
Pull deny_write_access revert from Christian Brauner:
"It turns out that the mold linker relies on the deny_write_access()
mechanism for executables.
The mold linker tries to open a file for writing and if ETXTBSY is
returned mold falls back to creating a new file"
* tag 'vfs-6.13.exec.deny_write_access.revert' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs:
Revert "fs: don't block i_writecount during exec"
