Nov 22, 2024 Fixed a complie error when FF_FS_LOCK != 0. (appeared at R0.15) Fixed a potential issue when work FatFs concurrency with FF_FS_REENTRANT, FF_VOLUMES >= 2 and FF_FS_LOCK > 0. Made f_setlabel accept a volume label with Unix style volume ID when FF_STR_VOLUME_ID == 2. Made FatFs update PercInUse field in exFAT VBR. (A preceding f_getfree is needed for the accuracy)

<p><em>Remarks: This function needs to be under control of FatFs module. Application program MUST NOT call this function while FatFs is in use, or FAT structure on the volume can be broken. To re-initialize the filesystem, use <tt>f_mount</tt> function instead.</em></p>
