fs: rename generic_delete_inode() and generic_drop_inode()

2025-09-15T14:09:42Z

generic_delete_inode() is rather misleading for what the routine is doing. inode_just_drop() should be much clearer. The new naming is inconsistent with generic_drop_inode(), so rename that one as well with inode_ as the suffix. No functional changes.

USB: gadget: Replace deprecated strncpy() with strscpy()

2025-04-11T14:08:33Z

strncpy() is deprecated for NUL-terminated destination buffers; use strscpy() instead. Since kzalloc() already zeroes out the destination buffer, the potential NUL-padding by strncpy() is unnecessary. strscpy() copies only the required characters and guarantees NUL-termination. Since the destination buffer has a fixed length, strscpy() automatically determines its size using sizeof() when the argument is omitted. This makes an explicit sizeof() call unnecessary. The source string is also NUL-terminated and meets the __must_be_cstr() requirement of strscpy(). No functional changes intended.

USB: gadget: Use str_enable_disable-like helpers

2025-01-15T17:28:13Z

Replace ternary (condition ? "enable" : "disable") syntax with helpers from string_choices.h because: 1. Simple function call with one argument is easier to read. Ternary operator has three arguments and with wrapping might lead to quite long code. 2. Is slightly shorter thus also easier to read. 3. It brings uniformity in the text - same string. 4. Allows deduping by the linker, which results in a smaller binary file.

[tree-wide] finally take no_llseek out

2024-09-27T15:18:43Z

no_llseek had been defined to NULL two years ago, in commit 868941b14441 ("fs: remove no_llseek") To quote that commit, At -rc1 we'll need do a mechanical removal of no_llseek - git grep -l -w no_llseek | grep -v porting.rst | while read i; do sed -i '/\/d' $i done would do it. Unfortunately, that hadn't been done. Linus, could you do that now, so that we could finally put that thing to rest? All instances are of the form .llseek = no_llseek, so it's obviously safe.

usb: gadgetfs: return USB_GADGET_DELAYED_STATUS from setup()

2023-10-02T14:43:05Z

Return USB_GADGET_DELAYED_STATUS from the setup() callback for 0-length transfers as a workaround to stop some UDC drivers (e.g. dwc3) from automatically proceeding with the status stage. This workaround should be removed once all UDC drivers are fixed to always delay the status stage until a response is queued to EP0.
